  • Q: Gaskets  BananaSammiches1 year ago

    Are TGV to cylinder head gaskets required for use these spacers or will the spacers themselves be enough to creat a proper seal?
    • 1 of 1 people found the following answer helpful

      A:  GrimmSpeed has installed both with and without OEM Subaru Gaskets and have had no issues with either way. They do recommend using 2 sets of oem gaskets however, one on both sides of the spacer.

  • Q: fp black turbo inlet  Mcmcll2703395324 years ago

    will the 3mm's be enough for an fp turbo inlet? or would 8mm be better? diameter is 84 mm.

      A:  The FP inlet is silicone and can be compressed to fit under the manifold, therefore 3mm spacers should be sufficient.
