Product Description

For 2002+ Subaru turbo 4-cylinder engines - WRX, STI, Legacy GT, and Forester XT.

  • New improved material!
    • Insulates 20% better than conventional phenolic spacers.
    • Higher heat resistance.
    • Better strength and mechanical properties.
    • Better chemical resistance
    • Cool Subie blue color.
    • No increase in price!
  • Includes 2 phenolic spacers and longer OE-quality bolts needed for installation (4 OEM gaskets are optional but recommended).
  • Made in USA from tough military-spec. phenolic composite - not cheap plastic like the others.
    • Phenolic has been used for decades to insulate intake manifolds. Even Ford SVO sells them.
  • 6.5mm thickness is recommended for modified cars with front-mount intercooler (FMIC) only.
  • Insulates the intake manifold and TGV housing from the heat coming up from the cylinder heads.
  • Reduces the intake manifold runner temperature keeping the charge air cooler and denser for more power.
  • CNC machined to match the head port (not the gasket) for smoothest flow. Ours are the only spacers like this.
  • These are the best-insulating spacers available for a Subaru anywhere.
  • For those with top-mount intercoolers (TMIC) these thicker spacers may cause misalignment problems. Please consider KSTech 3mm spacers .
