Professionally engineered performance for 500 - 725 horsepower applications utilizing 50 - 75 lb/min turbochargers.

The legendary APS front mount intercooler has quickly become the benchmark for all front mount intercooler systems for the STi. Extremely high flow rates and massive temperature reduction - a level of performance that other manufacturers can only aspire to achieve.

APS has now upped the ante even further with the release of the D/R 725 front mount intercooler system, specifically designed for very high horsepower Subaru STI engines.

Unlike other systems that require cutting of structural components at the front of the vehicle, APS has designed the D/R Series FMIC with a truly bolt-on replacement unit that not only maintains the structural integrity of the vehicle, but also forms the perfect mount to accommodate the largest FMIC available for a STI.

Another bonus for the Subaru performance enthusiast is that the APS D/R Series FMIC maintains the standard fog lights!

In the case of intercooling, where bigger is better, APS shoehorned the largest intercooler core possible into the STi for maximum cooling capacity and engine performance.

With intercooler core dimensions of 9.5" x 28" x 4.5" (24.1cm x 71.1cm x 11.4cm) for a surface area of over 266 square inches and a total intercooler core volume of 1,197 cubic inches (19,600 cm3) (the largest by far of aftermarket STI intercoolers) that's over 4.5 times the size of the standard top mount intercooler.
