Introducing our newest upgrade for your E36: a full billet aluminum valve cover engineered to eliminate factory and aftermarket valve cover issues. If you're familiar with our new Turner Motorsport products for 2023 and 2024 you can tell that our engineering team at Turner has a focus on older chassis, especially the E36.

Our valve cover is designed to fit some of the best engines BMW ever came out with, single vanos M50/M52 and S50/S52. Not only are these great motors in general and deserve an upgraded valve cover but they are also prime for boosting. When adding boosting you will be introducing heat which can wreak havoc on your ignition system and make your factory valve cover extremely prone to failure. 

The reality of the M5x/S5x motors is that the plastic valve covers are sub-par and the magnesium versions are no longer available from BMW and even those can even warp. You can end up replacing your valve cover time and time again dealing with issues if you prefer but the option is here for you. The last valve cover you buy for your E36. 

Our engineers designed this valve cover with experience and personal passion that offers a plethora of benefits for your M5x/S5x motor. Whether you plan to cherish your E36 for years to come or envision a turbocharger upgrade, our valve cover is the ultimate solution. It boasts rugged durability and brilliant aesthetics, ensuring it's a perfect fit for any enthusiast.

Featuring full 6061 billet construction and a type-3 hard coat finish, our valve cover is built to endure extreme conditions and rigorous use. Whether you opt to retain your factory PCV setup or upgrade to a catch can for racing purposes, the cover provides dedicated, direct-fit ports for both configurations.

The base kit includes all the necessary components for a seamless installation. Additionally, the description provides part numbers for optional replacements and add-ons, ensuring you have everything you need to complete your install.
