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.

Over time, your engine timing components begin to wear out. Tensioners weaken, chains can stretch, and timing chain guides can wear down. All of these lead to the possibility of the timing chain jumping teeth on the sprockets, causing your timing to shift. This could result in rough idle and reduced engine power, or even complete engine failure. Prevent damage to your engine with new timing components, such as this IWIS timing chain tensioner. Note, we recommend replacing timing components every 100K miles, or sooner, depending on the condition of the timing components.

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. MMX has produced a EN36 machined billet one-piece crank hub heat treated with a 0.75mm case hardening which makes it extremely durable. Due to the one-piece design, it ensures that the friction plates cannot slip. This offers a huge jump in reliability when paired with a new properly torques crank bolt. Installation is requires no drilling or modification to the OEM crankshaft ensuring a perfect fit! Can also be paired with MMR's Performance Capture Plate to ensure against loosening of the crank bolt. *Installation recommended by a professional shop or technician.

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.
