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.

The alternator in your vehicle keeps the battery at full charge when your engine is running. Because all of your electronic systems run off of this small piece, it's important that it is operational. If your lights are dim while driving or your battery dies within minutes of starting your car, it's time for a new alternator.

This is a NEW alternator from the OEM manufacturer, Valeo. No core charge applies. Valeo is an OEM manufacturer for many BMW alternators - save money by buying the same alternator in a different box!

Condor's Engine Mount Heat Sleeves reflect up to 90 percent of radiant heat. They withstand 1,100 degrees F of radiant heat and up to 450 degrees F of direct heat. The extra protection of the heat sleeves is a perfect fit for street cars, track cars, and other high heat applications. Their mounts withstand temperatures up to 180 degrees F and do not need any heat protection during regular usage, but we recommend the extra protection of their sleeves for all vehicles with high underhood heat temperatures such as turbo and supercharged vehicles. Condor heat sleeves can be easily installed by simply slipping the sleeve around the engine mount and securing using the Velcro tabs. *LISTING IS FOR ONE HEAT SHIELD **Heat sleeve fitment is for Condor Engine Mounts only.

This is the coolant temperature sensor used in many BMW models from the late-1990s to the mid-2010s. The engine computer relies on the coolant temp to set the fuel mapping for the engine. As the car warms up the computer changes the fuel mixture. If your car is running a bit rich (too much fuel) it could be because this sensor is failing and not sending the correct info to the computer. This sensor is located in a variety of places depending on the engine. But it's one of those easy replacement items 'while you're in there' when doing a water pump or thermostat replacement. From 1974 to 2019, Bavarian Autosport was one of the premier vendors for BMW and MINI auto parts.
