These fuel injectors, Bosch part# 0 280 155 968, are very popular in many forced induction setups, as they flow enough fuel to prevent detonation at high rpm, and maintain adequate fueling. To use these on a BMW, you must have specialized tuning, as these provide far too much fuel with a stock or naturally aspirated setup. These injectors are often referred to as the "green top" or "green giant" injectors, which are also used in Ford Mustang Cobra applications. This newer generation fuel injector replaces the older style (and now discontinued) EV1 fuel injectors, often referred to as the Ford Racing EV1 fuel injector or M-9593-F302 ). They are rated at 42# / 42 pounds @ 2.7 BAR. In a BMW, which has a 3.5 BAR system, they provide approximately 47 PSI. These are sold individually, so be sure to order enough for your needs.

This is the OEM Bosch ignition coil that is the current replacement for most BMW 6 and 8-cylinder engines built since 2003. It's listed as a replacement coil for M54, M56, S54, N52, N54, N62, N63, N73, S63, S63TU and other engines. BMW has made numerous changes to ignition coil part numbers in recent years but has approved this part number to work in the vehicles listed in our fitments tab. This part number replaces previous BMW part numbers 12130390064, 12130148594, 12131712219, and 12137551260.

Ignition coils are key to the efficiency and performance of your BMW. With a faulty coil the spark plug is not burning the air/fuel mixture properly and that can lead to problems anywhere in the engine and exhaust (including catalytic converters and O2 sensors). Problems with one or more coils will cause a fault code but not always a check engine light. A misfire code may be related to an ignition coil but could be from other things as well. Sometimes a visual inspection of a coil and coil boot will give an indication of a failure. You can also move coils around to different cylinder banks to see if the misfire code follows a suspect coil. We suggest always having one or two coils on hand to keep as spares.

This Bosch part also satisfies BMW's service bulletin for 2001-2003 E46 M3 ignition coils (SIB 12 24 05). That SIB calls for Bremi or ERA brand coils but BMW has replaced them with this Bosch design.

Bosch is one of the largest OEM producers of Genuine BMW and aftermarket parts in the world, providing parts for almost every major automotive manufacturer. Bosch has likely supplied many of the original electrical (and mechanical) parts for your BMW. Thanks to their quality, high durability, and reliability, you should expect a long service life from Bosch products.

As a leading source of high performance BMW parts and accessories since 1993, we at Turner Motorsport are honored to be the go-to supplier for tens of thousands of enthusiasts the world over. With over two decades of parts, service, and racing experience under our belt, we provide only quality performance and replacement parts.  All of our performance parts are those we would (and do!) install and run on our own cars, as well as replacement parts that are Genuine BMW or from OEM manufacturers. We only offer parts we know you can trust to perform!

Sold per coil. Includes connecting boot.

Includes a full set of polyacrylic intake and viton exhaust valve stem seals! Looking to replace your valve stem seals due to leaks, cracks, splits, or even during an upgrade of your camshafts, valve springs, or valves? Supertech valve stem seals are the way to go! This cheap but effective seal replaces the stock BMW seals that are notoriously prone to issues due to heat cycles and chemicals which cause the seals to become weak and brittle. Supertech seals offer a significantly longer life span and are resistant to both heat and chemicals thanks to their use of Viton or Polyacrylic construction (dependant on valve type). That means less time in the garage and more time on the street or track! These seals are also great for anyone who is looking to upgrade to dual valve springs thanks to the seal's overall thinner outer diameter! Guide OD: 8.8mm/.347" Seal OD: 12.2mm/.480"

Now that BMWs popular S54 engine (found in the 2001-06 BMW M3, 2001-02 MZ3 and 2007-08 MZ4) are getting older, it's important to keep an eye on particular items. One such point is the S54 Vanos oil line. Normally thought of as a worry-free item, it has proven to put the damper on many track days. Rogue's stainless steel braided VANOS line replaces the factory BMW part number 11367837614 (current MSRP from BMW is $128.08!) The high pressure (1200psi) control system of the S54 vanos system is used to ensure responsive and accurate camshaft adjustments. The added complexity of the high oil pressure used on the S54 vanos means more opportunities for failures. Some customers have encountered the high pressure hardline fail at the track, spraying oil all over their engine compartment, ending their day. Rogue Engineering's S54 Vanos Oil Line is built in their Upper Saddle River, NJ facility, and tested to over 3000psi. Using their stainless steel braided hose with the proper banjo fittings, this a direct replacement for the factory line. Like the factory line, the lower portion of the line uses a heat sleeve from additional heat from the VANOS pump itself. Fits the following BMWs: 2001-06 BMW E46 M3 2001-02 BMW MZ3, including coupe and convertible 2007-08 BMW MZ4, including coupe and convertible

NOTE: These bearings are now sold as SP1534F which features a new and improved silver oxide coating that is stronger and more durable! Designed and manufactured by Clevite to BE Bearing specifications. These bearings replace the factory BMW rod bearings. The original BMW bearings have too little clearance, which leads to premature bearing wear and can cause early engine failure. Furthermore, the factory BMW bearings are made from tin-aluminum which are 5-times harder than a softer lead-copper bearing design. A softer bearing is better for your engine and more tolerant of foreign particles suspended in your oil. These BE Bearings feature a state-of-the-art Clevite Tri-Metal design with the Clevite Tri-Armor(tm) coating. Lead-copper design for greater durability and easy tracking with oil analysis like Blackstone (recommended). Designed with extra clearance to "fix" the BMW rod bearing design flaw. Designed for use with factory 10W60 weight oils. Tri-Armor coated for low conditions during cold start Ideal for start-stop vehicles Applicable for BMW engines S54 Standard size Sold as complete set (6-cylinders) Fits the following BMWs: 2002-2006 E46 BMW M3 S54 2002-2003 Z3 BMW M Coupe, M Roadster S54 2006-2008 Z4 BMW M Coupe, M Roadster S54

Rogue Engineering has developed a power pulley kit that reduces the drag on specific pulleys while allowing others to remain at their same efficiency. This allows for perfect operation in daily driven vehicles without a hiccup or stutter. However, when the demand for power is requested, the power pulley kit allows for the freed power to become apparent.  The term "power" pulley is a bit of a misnomer. Underdrive pulleys actually free up power by reducing the drag caused by the accessories.  These pulleys are based off a calculated percentage from factory dimensions, so that particular component speeds are safely reduced without affecting their true purpose.

Rogue Engineering Power Pullies are CNC machined from 6061-T6, heat treated aluminum and specially coated with a MIL-A-8625 Type III hard coat anodize finish. This kind of anodizing is not to be confused with a Type II cosmetic anodize finish (typical colors such as red, blue, silver, green, etc.). The hard coat anodize finish actually builds a small surface layer on top of the aluminum, preventing wear.

This part fits the following BMW engines:
S54

This part fits the following chassis:
E46, Z3, Z4

Upgraded valves designed for high horsepower applications! Our valves are not finished from generic blanks rather they are specifically designed for each and every application. We work relentlessly, testing and researching every aspect trying to improve the air flow of our designs. With every valve design, we strive to maximize durability through higher fatigue resistance and tensile strength. Each valve tip is hardened beyond 52HRc. It’s unlikely you will find any of our competitor’s valves with stricter dimensional tolerances than our Supertech valves. Combine that with finished seats with equally strict run out tolerances and you won’t find a better sealing, better performing and easier to install solution anywhere! Optimum high flow rates are achieved by ensuring that our valves are manufactured with the best angles for each application. We consider back cut, under cut and valve head angles for each application to produce the optimum high flow rates for each application. In 2006 we introduced our stem Superfinishing as a standard addition to all of our valves at no additional cost. When our Superfinish is combined with our Black Nitrided valve, it reduces the surface roughness to 1/3 of our chrome coated valve. The end result… unsurpassed performance and durability. Our exhaust valves are made from EV16 (21-8N) or EV8-Nb/w for greater strength at higher temperatures. Black Nitride Coating: This is a hardening treatment that has been steadily growing in popularity over the last several years. These black Nitride coated valves feature harder surfaces and smoother finishes, providing less friction and subsequently longer life. Please see below for more benefits of our Black Nitride valves.
