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.

If a solenoid valve needs to be replaced, this part is appropriate for both situations, outlet and inlet. Two required per car.

BMW has an ongoing issue with oil separators freezing in cold weather if driving is done before the vehicle is fully warmed up. There is often a howling noise followed by numerous oil leaks. The crankcase breather valve is used to purge the oil vapor from the engine block into the valve cover. However, sometimes condensation can cause it to freeze, causing the entire oil separator system to fail, crack, and disintegrate. Replace this and all the other components of the oil separator system to prevent damage to all the aspects of your engine. As long as you have everything off, you can rest assured that new parts will last and be reliable. 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.

We have seen so many M52/M54/S52 Vanos line failures at the track that we have to offer you a solution. The factory line is prone to failure due to the OEM hard-line - this rubber line alleviates the issues imposed by the factory design and enables you to worry less about your Vanos system. We trust ECS Tuning's Exact-Fit Stainless Steel lines for several different applications, and their M52/M54/S52 Vanos line is no exception. Bavarian Autosport's M52/M54/S52 Exact-Fit Rubber Vanos Line offers several benefits over OEM. Not is it they more durable and reliable OEM, but it is also easier to install, and significantly less expensive than the factory BMW Vanos line (11361705532) or other alternatives available on the market. If you're factory Vanos line hasn't failed yet, we still recommend replacing yours with Bavarian Autorsport's Exact Fit Rubber Vanos Line M52/M54/S52 to avoid eminent future failure.

RACING SPARK PLUG FOR M50/M52/M54 ENGINES
These spark plugs are recommended by BMW Motorsport for use in their DTC racing engines. We find a slight horsepower increase and greatly increased durability over the OEM road car spark plugs in competition use. We attribute the improvements to the fact that these spark plugs are designed for the high temperatures and cylinder pressures encountered in a racing engine. These spark plugs are a direct replacement and come pre-gapped just like the factory road car plugs.
Please note: these plugs are not for the S54 engine in the E46 M3, MZ3, or Z4 M
