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.

Since 2010, Advanced Auto Fabrication has been producing and developing both parts and full fledged race cars. Their knowledge base covers a wide range of vehicles both domestic and imported. In the specific case of BMW, the team at AAF has a particular affinity for building and designing components for BMW race cars. The AAF E46 Jump Post Relocation Bracket makes it easy to adjust camber/caster on your race car by getting the factory jump post out of the way! In race car applications, the desired camber and caster settings can cause the strut tops and shock adjusters to interfere with the factory jump post. This kit takes just a few minutes to install and makes using strut braces and adjusting camber plates just that much safer and faster.

In the specific case of BMW, the team at AAF has a particular affinity for building and designing components for BMW race cars. This oil pan baffle by AAF keeps the oil at the pick up better than others on the market. Baffling the oil pan is extremely important. Under racing and track conditions, oil can move in the oil pan enough to cause extended moments of oil starvation. This can cause premature, and in some cases immediate, engine failure. The pan features a tight fit to keep oil from exiting under braking or cornering. A must have for all track cars.
