Compact design that features black anodized aluminum for a very clean finish. We have taken it one step further and matched the bottom of the plug to the diameter of the Subaru intake piping so the plug is not in the way of flow!



  • Easy to Install: under 2 minutes for installation
  • O-Ring for a perfect air tight seal
  • Compact, clean, and proudly displaying the GrimmSpeed Logo
  • Logical Design
  • Plate is curved to fit piping for no intrusions into the flow path
