Restore proper oil system sealing and eliminate chronic weeping from the engine bay with a billet aluminum replacement designed specifically for BMW N54, N55, S55, N51, N52 and N20 platforms. The original plastic housing cap frequently degrades under extreme thermal cycling, leading to costly rear main seal contamination and repeated maintenance visits. This direct-bolt upgrade features precise machining to OEM tolerances, utilizing a durable viton o-ring and a black corrosion-resistant finish that outlives standard factory parts while maintaining exact clearance around the front filter access point.

Key Benefits & Installation Tips

  • The upgraded vitamin o-ring maintains consistent compression across wide temperature ranges, effectively halting slow drips that typically develop around the factory filter cover.
  • This cap is engineered to reuse your existing center cage and filter bypass valve assembly; simply remove the metal core from your worn oe cap and snap it into the new billeted housing.
  • Always coat the o-ring groove with fresh engine oil before final tightening to prevent twisting during assembly and ensure a uniform seal during subsequent oil changes.
