Add a consistent 10+ wheel horsepowerwith one of the largest Top Mounted Intercoolers on the market! We pushed every dimension to make this the best TMIC for your WRX!

It’s HUGE!
A larger core means less restriction and better cooling capabilities for more horsepower. Our core size is 10.24″ wide x 13.62″ deep x 3.75″ thick, making the volume just over 523 cubic inches.

Cooler Charge Temps Means More HP!
Rated well over 500WHP, the PERRIN cores extra-large cross-section and cooler charge temps will add horsepower and keep up with all your performance upgrades.

Design
The Perrin Intercooler Core is 66% larger then the stock intercooler and features a higher flow design and more consistent horsepower gains when compared to other cores.

The 3/8″ Bar and Plate design is more durable than the traditional tube and fin and more free-flowing than other cores.

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.

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.

The Top Mount Intercooler is designed to fit perfectly with the PERRIN Strut Brace and Intercooler Shroud!

Pressure Testing

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

No Tuning Required!

Increase horsepower and torque without ECU recalibration or tune! This part is designed and tested to work safely on your vehicle without any tuning required. However, more power can be gained with proper ECU tuning.

Throttle Body Couple Included

For convenient installation and removal, a PERRIN Throttle Body Coupler is included with each TMIC. Our silicone couplers are made from fiber-reinforced 3-ply silicone tubes. The high-strength, multi-layer design is designed to withstand high pressure and temperature.
