What is the primary function of this intercooler?

This air-to-air intercooler cools the compressed air from your turbocharger or supercharger before it enters the engine. Cooler, denser air allows for more oxygen in the cylinders, which can lead to increased power output and better engine efficiency.

What does 'not CARB approved' mean for this part?

CARB (California Air Resources Board) approval is required for emissions-related parts sold in California. This intercooler is not approved, meaning it cannot be legally sold or shipped to California residents due to emissions regulations.

What horsepower range is this intercooler designed for?

This specific Garrett intercooler is rated to support vehicles producing up to 425 horsepower. It's a good choice for moderately modified engines looking to improve charge air cooling.
