Introducing our infamous 2002-2007 Subaru WRX STi intercooler kit. This heavyweight is measured at 28″ x 4.5″ x 10.5″ and can handle up to 900 HP and 938 CFM flow rate at 1.5 PSI pressure drop without even coming close to over-stressing your engine. Our kit has been tried true by some of the industries best tuners on both track and strip and is private labeled across the world. We’ve designed our kit to relieve the threat of heat soaking: making it the last worry on your mind.

Some key features integrated into our design is a built in front-frame-brace which replaces the bumper support and fortifies front structural integrity of your vehicle. Our intercoolers enlarged internal surface area provides superior cooling efficiencies for radiating heat excess and minimizing heat soak. Another detail worth mentioning–to sell the idea of superior engineering–our replacement front-frame-brace comes grooved around welding strips to avoid rubbing caused by vibration, therefore ensuring no development of micro-fissures. Pretty much if you’ve thought about a common or sophisticated problem, we’ve thought about it even longer and have developed a truly flawless product.
