Billet Aluminum Oil Filter Housing For BMW N54 N55 S55

Upgraded billet aluminum housing stops factory filter casings from cracking or leaking under sustained pressure. The direct replacement mates cleanly with your BMW’s N54, N55, S55, N51, N52, and N20 engine blocks. You gain better heat transfer and consistent oil flow without chasing persistent drops.

This precision-machined front cover keeps your original bypass cage intact. Simply move the OE center valve into the new black-anodized cap and reuse the supplied Viton seal. Thick alloy walls resist flex during aggressive driving or hot summer commutes. Swap filters faster when thick knurling gives you solid grip in tight engine bays.

Benefits & Tips

Wipe the engine mating flange clean before sliding the new housing onto the studs. Lightly coat the Viton O-ring with fresh motor oil to prevent rolling during installation. Hand-tighten until seated, then follow your service manual torque values to protect the seal.
