Give your 2015–2020 BMW M3/M4 the protection it deserves with the Mishimoto Baffled Oil Catch Can Kit. The introduction of the S55 into the M3 and M4 in 2015 was the first time compact M’s saw turbos from the factory, but these engines brought along another long-standing tradition—blow-by. The Mishimoto BMW M3/M4 catch can kit uses proven engineering from the patent pending Mishimoto 2-Port Compact Baffled Oil Catch Can, with its 50-micron bronze filter and internal baffle, to better separate the oil from the crankcase vapors. The engineers at Mishimoto designed a CNC-machined lid that features large inlet and outlet ports to match the inner dimension of the CCV hose. This baffled oil catch can defends your intercooler, intake system, and VANOS system from oil blow-by and helps maintain proper octane levels to reduce potential detonation. The kit comes with two direct-fit hoses, which require no modification to the engine cover, and one direct-fit billet aluminum mounting bracket that is extremely easy to install and mounts the can in a serviceable location! Two aluminum, 3/4” barb fittings connect the hoses to the can. And, like every Mishimoto oil catch can, this baffled catch can kit comes with the Mishimoto Lifetime Warranty! Our catch cans are different from most air-oil-separator (AOS) systems on a few levels. First, our catch cans are not heated. This means that all of the blow-by is able to condense in the can, including low-octane oil vapors and contaminated fuel vapors. Most AOS systems also drain the blow-by back into the oil pan, while our catch cans trap the blow-by and keep it out of the engine permanently. If you’ve seen what we’ve seen in the bottom of our catch cans, you won’t want that draining back into your oil either. *After installation, Mishimoto recommends checking the contents of the baffled catch cans every 1,000 miles until a baseline is established. Oil blow-by accumulation will vary with ambient temperatures and driving conditions. It is important that the contents of the can do not rise above the internal baffle* Features: Direct fit for the 2015–2020 F8X BMW M3 and M4 Single can mounts in line with the CCV system to separate oil from air using a 50-micron bronze filter Helps reduce carbon buildup on intake valves Patent-pending billet 6061 aluminum can sealed with Viton™ O-rings Installs in under 30 minutes Robust CNC-machined anodized aluminum bracket mounts the can in a serviceable location Includes pre-molded hoses for simplified installation Defends Vanos system and essential engine components from oil blow-by CNC-machined aluminum barbed fittings ensure a sturdy connection between lines and can Catch can has a 3 oz. capacity for longer servicing intervals Internal air diverter increases air turbulence to improve oil separation Helps maintain proper octane levels to reduce potential detonation Filter and can are fully serviceable Mishimoto Lifetime Warranty Included: (1) Compact Baffled Oil Catch Can (1) Application-Specific Mounting Bracket (2) Direct-Fit Hoses (2) 3/4" Aluminum Barbed Fittings (4) Worm Gear Clamps Mounting Hardware Mishimoto Lifetime Warranty WARNING!

The BMW N52, N54, N55, & S55 engines are notorious for random serpentine belt failures. Once this belt fails on your engine, there is a strong possibility for it to wrap around your crank shaft past your OEM crank seal, and into your engine internals. Once the belt is inside your engine, it is commonly shredded, causing bits and pieces to clog up the oil pickup and potentially lead to catastrophic engine failure. The 034Motorsport Billet Crank Seal Guard is designed to be installed over the OEM BMW crank seal to prevent a failed serpentine belt from entering your engine. The 034Motorsport Crank Seal Guard is manufactured from 6061-T6 billet aluminum and anodized black to protect it from any corrosion. FEATURES: Prevent the Dreaded and Costly Premature Serpentine Belt Failure From Ending Up in Your Oil Pan, Leading to Oil Starvation and Engine Failure Machined from 6061-T6 Aluminum Anodized Black for Protection from Corrosion & Long Lasting Great Looks WHAT’S INCLUDED: 1x) 034Motorsport Billet Crank Seal Belt Guard 2x) M8x1.25x40mm - 12.9, Zinc Plated Screws

Each oil filter cap is CNC milled from a solid block of billet aluminum and fitted with a Samarium-Cobalt rare earth magnet. This magnet is in direct contact with pre-filtered oil, as a result, the magnet will naturally capture Ferrous particles within your engine oil. Ferrous particles in engine oil cause premature wear, obstruct the paper oil filter, and could be an indication of a serious issue within your engine.

VTT is proud to offer its very own Game Changer S55/N55 to B58 Coil conversion kit for the BMW S55/N55 platforms. The 55 series of engines has notoriously had ignition problems with the factory coils, while aftermarket upgrades do exist, they can be bulky. The solution is the BMW B58 ignition coils which are extremely robust and can support well over 1000WHP with no issues. This means a plug-and-play affordable solution that fits like stock, and looks AMAZING doing so! We designed our own 6061-T6 Billet bracket in a plethora of colors including matching shades for every S55/N55 Valve Cover. This means you can mix and match the color of the bracket with coil color, with VC color to truly tailor your engine bay to look exactly how you want it to! The kit comes with the following: 3 – Billet Aluminum Coil Brackets in the color of choice 6 – Plug and play VTT wiring harnesses 6 – Custom VTT stalks to convert the B58 coils to the S55/N55 head (We ensure proper spring length inside the boot for optimal spring-to-plug contact) *NOTE: Flash setting changes may be required when installing the conversion kit to ensure the proper function of the B58 coils with S55/N55 DME. This can be found in almost all flashing software settings such as MHD, Bm3, etc.* **NOTE: THESE BRACKETS FIT STOCK S55 VC, VTT S55 BILLET VC, and MOST N55 made after 2011. If you have an older N55 made before 01/2011. These may not fit. Purchase carefully as items that have been installed or attempted to cannot be returned.**

Add some much-needed durability and cooling power to your M3 or M4 with the Mishimoto 2015-2020 BMW M3/M4 Oil Cooler. True to form, the engineers at BMW designed the M3/M4’s oil cooler with efficient use of space in mind. Suspended perpendicular from the rest of the cooling stack, this location utilizes the Bimmer’s aerodynamics in order to cool the oil, all while putting the lightweight, tube-and-fin cooler in harm's way of road hazards. We here at Mishimoto made sure to beef up the oil cooler design for the F80/82 with our performance oil cooler. We ditched the lightweight design for a full aluminum, TIG-welded bar-and-plate cooler for added strength and cooling. The bars and plates are a much more robust form of heat exchanger core construction intended for improved heat transfer and have the strength to shrug off potential road debris, keeping your oil temps down, and where it should be. We also added 10mm to the core’s thickness, equating in a 46% increase in core volume, and increased the oil capacity by .4 qt. The Mishimoto 2015-2020 BMW M3/M4 Oil Cooler fits directly in place of the stock unit, and includes the Mishimoto Lifetime Warranty for a simplified and worry-free installation. Features: Direct fit for the 2015–2020 BMW F8X M3, M4, and M2 Competition Full aluminum TIG-welded construction 46% increase in core volume Increases oil capacity by .44 quarts Robust bar-and-plate construction for improved durability and heat rejection Silver powder-coated finish for maximum protection No cutting or modifications required Mishimoto Lifetime Warranty Included: (1) Performance Oil Cooler (2) Replacement O-Rings Mounting Hardware Mishimoto Lifetime Warranty WARNING! Prop 65 may apply to this product. Proposition 65 (Safe Drinking Water and Toxic Enforcement Act of 1968) is a California law that applies to call companies selling products in California.

Anyone with a modified S55 knows the risks involved with the OEM Crank Hub. When the engine simply can't handle the stresses its put under or the design is such that it simply does not support extreme conditions, issues can arise. Under certain conditions, the S55 crank hub likes to spin, without warning and even when the engine is in perfect health. MMR has produced a T-6061 machined billet aluminum capture plate anodized in their trademark finish. The MMR Performance capture plate secures the head of the OE crank bolt and prevents it from turning or being able to loosen. This capture plate can be secured to the OEM crank bolt or to MMR's redesigned one-piece crank hub. *Installation recommended by a professional shop or technician.

Powerflex is the number one selling suspension bushing manufacturer in Europe. Their experience with polyurethane bushing material and state-of-the art manufacturing techniques allows them to produce premium performance bushings, made to exact-fit standards. Powerflex performance polyurethane bushings are built to last longer than OEM rubber bushings, while improving performance and allowing for a more engaging driving experience. Powerflex is pleased to introduce their new S55 Engine Mount Inserts, intermediate alternatives to the BMW aluminum inserts and much stiffer full replacement engine mounts available on the aftermarket. Made in Black 70A durometer material, they are designed to fit the OE mounts snuggly to restrict engine movement with a minimal increase in NVH, perfect for those with tuned road cars. Their design and flexibility also mean they can be fitted to the vehicle without removing the engine mounts themselves. Reducing engine/transmission movement by way of upgraded inserts has the following benefits: Sharper throttle response Improved gear shifting More direct power transfer More balanced on/off throttle handling Prolonged life of the OE mounts *Yellow version pictured for installation reference A small increase in NVH, usually at idle, should be expected when stiffening the connecting mount between the engine and chassis. The harder the material used, the greater the NVH transmitted.

These high flow injectors flow 85% over stock! Each injector is tested and calibrated using state of the art high pressure flow calibration equipment and then matched to a set of 6. Installation of these is a snap and is as simple as replacing your injectors, a little coding, and then checking a checkbox!

Both the N55 and S55 engines are plagued by the same issue when chasing high horsepower numbers... the dreaded crankhub failure. Fortunately MMR Performance has released an upgraded version of their already stout single-piece crankhub, but this time offering a 4-pin dowelled location that locks onto the front of the crankshaft. This configuration eliminates the multi-piece crankhub with friction discs in favor of a more robust single piece crankhub. Recommended for high-powered cars over 700 Horsepower

Under certain conditions, the N55 crank hub likes to spin, without warning and even when the engine is in perfect health. The engineers at Vargas saw and dealt with this problem time and again, and they saw fit to do something about it. This hub uses a proprietary "Spline Lock" technology that uses high tolerance machined splines which press into the crank, and positively lock the hub to the crank. The splines are machined in such a way that rotational forces drive the hub, and splines deeper into the crank meaning when the hub encounters a situation that would normally slip a stock hub the splined hub is driven into the crank to keep it in place (much like a splined extractor). Features: Installs the same as a stock hub Does NOT require the crank to be drilled for pins Manufactured from Harndered 17-4SS We suggest the Crank Hub System ONLY be installed by a qualified shop or technician. Timing tools are 100% REQUIRED if installed improperly engine damage may occur. DISCLAIMER: VTT and ECS are not responsible for any engine damage caused by improper installation, or misuse of the crank hub solution.

Paradigm Engineering’s magnetic oil filter cap augments your vehicle's oil filtration system and serves as a diagnostic tool. Each oil filter cap is CNC milled from a solid block of billet aluminum and fitted with a Samarium-Cobalt rare earth magnet. This magnet is in direct contact with pre-filtered oil, as a result, the magnet will naturally capture Ferrous particles within your engine oil. Ferrous particles in engine oil cause premature wear, obstruct the paper oil filter, and could be an indication of a serious issue within your engine.

The S55 engine is no stranger to oil cooling problems, that’s why we recommend installing the MSL Oil Thermostat. The standard oil thermostat will reach around 120 degrees Celsius with a normal driving style. The MSL Oil Thermostat will open at a lower temperature than the standard oil thermostat (at 85 degrees Celsius) and will keep the temperature stable between 95 and 105 degrees Celsius. Installing the MSL thermostat ensures a cooler oil temperature which will result in more stable performance, but above all this improves the reliability of the engine. It is recommended to install the thermostat, especially for cars that are tuned.

If you are breaking crankshafts and oil pumps, the cause may be a mystery to you as it has been to many of our customers. We know that controlling the harmonic resonance of the BMW 6 is highly important as RPMs rise, but the ideal configuration of the inline-6 motor makes even experienced engine builders overlook some fundamental principals of engine harmonics that can be destructive. ATI Performance Products has partnered with VAC Motorsports to develop new dampers for BMW 2.5L, 2.8L, 3.0L and 3.2L straight-6 engines found in the E36 and E46 M3, E9X and E6X, as well as newer Z3s and Z4s. These dampers eliminate crankshaft harmonic vibration, which allows the engine to produce more horsepower and torque, while also reducing internal engine wear at the same time. Broken oil pumps and timing chains will be a thing of the past! When used with a VAC accessory pulley, these dampers are a direct replacement over the OEM balancer. They have a 7” outer diameter and include OEM style timing alignment tabs. BMW enthusiasts should know that all ATI Super Dampers exceed SFI 18.1 Safety Certification and are approved for competition. The advantages of the ATI SuperDamper include eliminating vibration issues with inline 6 engines equipped with lightweight clutch and flywheel assemblies, reduced bearing, engine accessories, oil pump wear, and compatibility with underdrive pulleys. Includes lightweight VAC Billet Crankshaft Pulley. Made in the USA.
