Oil Filter Housing Cap Billet Aluminum For BMW B46 B48 N47 N57 3.0L Engine Upgrade
Upgrade your BMW with a billet aluminum oil filter housing cap designed for engines in the B46/B48/N47 family and the N57 3.0L. This precision-machined upgrade replaces the stock plastic cap with a durable billet aluminum component, delivering a premium look and enhanced durability under the hood. It reuses the OE filter cage—simply remove the center cage from the original housing cap and snap it into the billet cap—so you keep the exact filtration path your engine relies on while enjoying a cleaner, more professional engine bay appearance. The anodized coating protects against oxidation, helping the cap maintain its finish even under high-heat, dusty, or humid conditions. The cap threads on just like your original factory cap, ensuring a secure seal and proper alignment with no modification needed to the mounting points. This front-placement cap is compatible with BMW 2.0L B46/B48/N47 engines and the 3.0L N57 engine, making it a straightforward upgrade for owners looking to refresh the engine bay and improve long-term reliability. Scope of supply includes 1x oil filter housing cap; center cage is not included for this kit.
