Billet Aluminum Oil Filter Housing for BMW N20 N26 N52 N54 N55 S55

Upgrade your engine maintenance routine with this billet aluminum oil filter housing cap. Designed specifically for BMW N20, N26, N52, N54, N55, and S55 engines, it swaps out quickly during your next oil change. You will notice less hassle when reaching for stubborn factory housings that often warp over time. The machined alloy handles intense heat cycles without bending or cracking. A constructed viton o-ring creates a tighter seal than standard rubber, keeping your service bay spotless. Your mechanic will appreciate how the unit accepts your original bypass cage, saving you extra trips to the supplier. Snap the stock center mechanism straight into place, and you are ready to run.

Benefits & Tips

• Hand-Tight Removal: Smooth billet edges let you unscrew the cap without struggling over stripped or rounded bolts.
