Professionally engineered performance for 350 - 525 horsepower applications utilizing 40 - 55 lb/min turbochargers.

The legendary APS front mount intercooler has quickly become the benchmark for all front mount intercooler systems for the Impreza WRX. 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 525 front mount intercooler system, specifically designed for high horsepower Subaru WRX and 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 WRX and STI. Even the stock fog lights are retained!

APS shoehorned the optimum sized intercooler core for the target power levels, but with the greatest frontal surface area possible.

This provides the maximum cooling capacity and engine performance and of course, killer looks. With intercooler core dimensions of 9.375" x 33.5" x 3.25" for a surface area of over 314 square inches and a total intercooler core volume of 1,020 cubic inches.

The APS intercooler core is of internally finned construction and offers significantly enhanced flow and heat exchange performance over the standard intercooler and other front mount intercooler systems, particularly at high charge air mass flow rates. Also, unlike other manufacturers of WRX intercoolers who reduce cost by using deeper cores of small frontal area, the APS D/R Series intercooler is designed with the optimum ratio of intercooler core surface area (over 314 square inches!) to intercooler volume (1,1020 cubic inches). The result is an intercooler system with outstanding flow and cooling performance, particularly at high engine horsepower levels.
