The GrimmSpeed Blow Off Valve Flange Gasket is a direct replacement of the OEM gasket to provide an optimal seal between your blow-off, or bypass, valve and the flange on your top mount intercooler. Not only is this gasket three times thicker, it also contains an inner metal layer which helps prevent blow-outs and overall creates a better seal for better protection against leaks. That's where the 3x thicker TMIC BOV gasket's extra thickness comes in handy!

  • 3 times thicker than the OEM gasket
  • Provides an optimal seal between your blow-off valve, and the flange on your top mount intercooler
  • Will work with other blow-off valves and aftermarket flange locations with the OEM flange type
  • Sold individually
