M5x Cutring Head Gaskets


This is our recommended head gasket for forced induction applications.

These gaskets feature a multi-piece design using stainless "cut-rings" which mechanically seal the combustion chambers around the cylinders.  These gaskets require no special machining and ensure tremendous sealing capability. We have personally tested these gaskets to over 1000whp and 50psi of boost. 

We  offer these gaskets for multiple applications, we generally recommending using a small oversize versus your bore diameter to allow for easy install. While exactly matching the bore is preferred installation becomes more difficult for the hobbyist


For reference:

  • Stock m52 bore: 84mm
  • Stock s50 bore: 86mm
  • Stock s52 bore: 86.4mm
