The STM Evo 7/8/9 Hard Core Intercooler is made in-house using massive 5" thick Garrett core rated for over 1260 HP. The STM Hard Core Intercooler is for serious drag builds. It comes standard with a 3" inlet and 3" outlet. It will not require cutting of the frame, but you will definitely need to trim your front bumper. The factory crash bar must be removed and the STM Front Bumper Support bar will NOT fit. Racecars only!
While the 4" STM Race Core has held its ground on the track for years, the 4G63 will always be in a state of evolution and we are seeing builds well over 1200 HP that have a significant need for a high quality intercooler that can keep up with demands.
Vehicle Fitment: 2001-2006 Mitsubishi Evolution VII VIII IX • Does not fit with factory crash bar • Does not fit with STM support bar • Does not fit the Cusco Power Brace • Racecars only!
Based in West Chester, PA, FAST WC is known for building and tuning real-world performance cars, not just listing parts online.

Why Drivers Choose FAST of West Chester
I can't recommend this place enough. Being able to trust a shop in the performance world is big. The 2hr drive to get there, is worth knowing the job will be done right. Very happy to have found this shop, to support my builds going forward.

I recently had the pleasure of working with FAST of West Chester for some performance upgrades on my 2022 WRX, and the experience was nothing short of exceptional. I opted for a Borla S-Type exhaust and Cygnus Coilovers, and the team at FAST nailed the installation, fitment, and setup to a T.
Adam Cranston
The team at FAST are excellence in every way. First, I consulted with Dave on mods for my HPDE track car. He listened and advised me on the best parts & mods to achieve my goals. He was patient & gave me space to research the options presented & worked with me through several changes before we built. Second, the build execution was flawless, proper heat shielding, bracing and poly everywhere. All components worked as advertised.

This place has been my go to shop for all things Subaru. From simple service to performance parts and tuning, they have been top notch.
William Brunell
Excellent shop. They installed a Cobb Stage 2 DP and Whiteline Sway bars and end links on my 2013 WRX. The work was done right and clean. The estimate was accurate. They were very knowledgeable, friendly and gave me the straight scoop on exactly what I was getting for the money and what I needed to get where I want to be with it. I'd recommend them to any car enthusiast.
