Add a consistent 10+ wheel horsepower with the largest Top Mounted Intercooler on the market! We pushed every dimension to make this the best TMIC for your STI!

It's Huge!

The PERRIN TMIC is 12% larger than the nearest competitor's core. The larger core means less restriction and better cooling capabilities for more horsepower. Our core size is 21.87" wide x 7.64" deep x 3.95" thick making the volume just over 660 cubic inches!

Dyno Proven

Rated well over 600WHP, the PERRIN cores extra-large cross-section and cooler charge temps will add an easy 10 WHP and keep up with all your performance upgrades.

Design

The PERRIN Intercooler Core is 75% larger than the stock intercooler and features a higher flow design and more consistent horsepower gains when compared to other cores.

Throttle Body Coupler

Included with each TMIC is a PERRIN Throttle Body Coupler. Our silicone couplers are made from fiber-reinforced 3-ply silicone tubes. The high-strength reinforced silicone's multi-layer design is capable of withstanding extremely high pressures and temperatures.h4 class="margin-bottom-small">Core Construction

The 3/8" bar and plate design is more durable than the traditional tube and fin and more free-flowing than other cores.

Cast Aluminum End Tanks

PERRIN End Tanks feature smooth, radiused corners that reduce air turbulence for additional horsepower. All threaded mounting holes have stainless-steel inserts for easy installation and superior holding power.

Intercooler Finish

Every PERRIN Intercooler Core features a powder coat finish to protect your intercooler from the elements. There are two finish options: bright silver or stealth black.

Pressure Testing

PERRIN is one of the only intercooler manufacturers who pressure test every intercooler to 50 psi. Even the slightest leak can bleed turbo boost pressure out of the intercooler and cause your vehicle to lose power.

Stencil

A free PERRIN logo intercooler stencil comes in every box! Simply peel, stick, and paint to easily add a PERRIN logo across the top of your TMIC.
