A simple yet effective upgrade, these Bav Auto High-Performance Ignition Coils feature modified core windings that offer increased firepower and promote a faster, more efficient burn. The result is greater low-end torque and increased horsepower in the mid to top-end. When used in a properly functioning engine, a noticeable difference can be felt. In addition to better torque and horsepower, fuel economy is also improved! These coils come with new spark plug boots. From 1974 to 2019, Bavarian Autosport was one of the premier vendors for BMW and MINI auto parts. We are happy to preserve the Bav Auto legacy by continuing to carry their high-quality products into the future. All Bav Auto parts will remain unchanged in design and sourced from the same OEM suppliers to ensure long-lasting reliability. We trust these parts, accessories, and upgrades so confidently that we back every Bavarian Autosport branded component with a 2-year warranty.

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.

Thanks to their quality, high durability, and reliability, you should expect a long service life from Bosch products.

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!

Schrick has developed this high performance rocker arm based on the original factory E46 M3 rocker (cam follower). Schrick coats the contact pad with a DLC coating for reduced friction and improved reliability. The stock S54 rocker arm is un-coated. With more aggressive camshafts there is much higher force and friction on the contact pad which will not only induce more wear on the rocker arm but also lead to higher temperatures and thinning of the oil in a critical spot. The Schrick rocker is preferred over the stock part with any of the more aggressive S54 cams (304/296 or high lift, etc). The DLC coating is extremely hard (DLC = Diamond-Like Coating) but with a graphite content that allows for low friction levels. The DLC coating resists oils and chemicals so it's perfect for an internal part like a cam follower.

New rocker arms are required with any new camshaft installation. Sold per rocker arm.

The Secondary Air Pump in a vehicle injects air into the manifold to recreate a lean condition which causes the catalytic converters to raise in temperature until they are at optimum efficiency. Some vehicles do not come equipped with EGR/SAI systems from the factory and instead use this plate. If the plate is corroded or missing, replacement may be necessary. Use with a new gasket to ensure a proper seal.
