Billet Aluminum Oil Filter Housing Cap For BMW B46 B48 N47 N57

Upgrade your BMW maintenance routine with a solid oil filter housing cap designed to last. Replace the fragile plastic factory part with a heavy-duty billet aluminum unit that resists cracking and stripping under demanding service intervals.

This cap fits seamlessly on BMW B46, B48, N47, and N57 engines. The precision-machined anodized coating prevents oxidation and keeps the surface smooth, giving your engine bay a sharp, professional appearance.

Installation saves time and money by reusing your existing components. Pull the center filter cage from your current cap and snap it directly into this billet housing. No extra hardware is needed, and no tools are required to move the cage over.

The threading profile matches the original equipment design perfectly. It bolts on smoothly without binding, ensuring a secure fit and consistent torque application every time you change the oil.

The durable aluminum body stands up to high engine temperatures where stock plastic may warp. You gain confidence knowing the housing cap will not deform during extended driving or spirited runs.
