WRX
Specification
Spearco's WRX intercooler kits feature the largest air-to-air, top-mount intercooler in the market. Utilizing the factory mounting points, the massive 4.5 in. thick unit bolts on easily without any modifications to the vehicle. Factory turbo piping and blow-off valves can be bolted on easily with standard hand tools. The massive 1,000 cfm intercooler offers a very low pressure drop and extremely low charge temperatures. Dyno results have shown performance improvements of up to 15 hp when compared to the stock intercooler. The kits come complete with clamps and silicone hose. Boost pressure can now be increased without the horsepower-robbing effects of the extreme charge temperatures normally associated with compressed intake air.

Aerodynamics is what separates the GT-K turbo line from the competition. Equipped with the latest HP CompressorWheels, designed to maximize efficiency at high boost pressures, and the F1 turbine wheel, created to capture the maximum exhaust gas energy and reduce backpressures, the GT-K family of turbos delivers unequaled performance. When paired with the Map Enhancement Porting of the GT-K compressor housings, these wheels flow huge volumes of air at high pressure ratios while still delivering a cool efficient intake charge.
