Elevate your engine's performance with a choice of compression ratios that suit your needs. Opt for stock compression when conducting a basic engine rebuild or for low boost turbo or supercharger applications. If you plan to run high-performance camshafts, added compression can significantly enhance your engine's capabilities. On the other hand, if you're aiming for a big boost turbo setup, low compression is the way to go. CP and this distributor have collaborated closely to bring you the finest pistons for your high-performance or racing engine. These pistons are meticulously crafted to meet the most rigorous standards and are unrivaled in quality. Piston Specifications: BORE: 84.5mm Rod Length: 135mm Compression Ratio: 8.8:1

Stock OEM hydraulic valve lifter for the M42 and M50 engines. These lifter buckets can last 150,000+ miles but then they no longer fit on the valve stem correctly and a ticking or knocking noise can result. If the lifter is no longer seated correctly, it can lead to the valve not opening correctly. Replacement is straight-forward but requires special tools for working with the M50 camshafts.

When doing any sort of repair or maintenance there is no replacement for genuine factory parts. Turner Motorsport carries the Genuine BMW brand with pride and has the parts you need to complete your next project with confidence.

Price is for one lifter (one per valve).

This item fits the following BMWs:
