If you're having boosting issues, and perhaps aren't hitting target boost numbers, then your factory intercooler couplers could be leaking from a hole or a tear. After a certain amount of time, the factory intercooler couplers can become weak, and will expand under pressure. The will eventually fail, and your car will not be happy about it. Luckily Grimmspeed has the right components to get your car back on the road again. Their Top mount Intercooler Silicone Kit has been fabricated from high-grade 5-ply silicone with smooth interior walls to minimize turbulence. These couplers also have heat resistant reinforcement properties which will provide longevity for long-lasting performance.
Stainless Steel High-Torque Clamps are provided to make for a ready installation. This particular kit will come with red or black couplers.
FITMENT NOTE: These are only confirmed for STI or Grimmspeed y-pipes and WILL NOT fit WRX or Forester XT intercooler stock y-pipes. The elbow coupler is sized to fit multiple turbo setups, some trimming may be required.
