About Billet Valve Covers

Rennline billet aluminum valve covers for air-cooled 911s, sold in pairs and listed by engine and position.

  • 964: upper (M11) and lower (M12) valve covers, and billet aluminum timing chain covers (M54).
  • 993: upper (M13) and lower (M14) valve covers.
  • 993 Turbo: lower valve covers (M15).

They are fully CNC-machined billet, a direct bolt-on replacement for the factory covers, machined to accept the reusable OEM gaskets, with a corrosion-resistant finish.

Also listed: Rennline timing chain covers (M28). Upper and lower covers are separate listings, and each title gives the SKU and position — check the fitment on the listing before ordering.
