Key Features:

Performance Testing:
This intercooler kit has undergone rigorous testing on both stock and modified vehicles, proving to increase power and lower AITs significantly. For instance, on a 305 hp test vehicle running 20-22 psi of boost, the intercooler provided:
- A 14 hp increase in power
- A 30 degree drop in air intake temperatures compared to the stock STI intercooler
Durability & Warranty:
Thanks to its precision-engineered core construction, this intercooler kit supports vehicles with up to 350 hp. It is available in either a Stealth Black or Sleek Silver finish and comes with the Mishimoto Lifetime Warranty, signifying exceptional product quality and craftsmanship.
