A completely new APS High Flow Cold Air Intake system delivers a huge straight-shot of chilled fresh air directly into the wide compressor mouth of the APS TSR turbocharger.

The APS cold air intake system accommodates stock style MAF metering through the MAF venturi supplied with the APS system. Best of all, for those Subaru horsepower enthusiasts who overwhelm the stock MAF meter at extreme horsepower levels, the MAF venturi is removable and markedly increases the cross sectional area at the MAF metering point. This now gives huge headroom for even greater air flow, larger fuel injectors, more effective air flow metering at high horsepower levels - and of course far greater tunability from the MAF meter.

Ultimately, a complete extreme horsepower turbocharger solution that leaves nothing to chance. Highly engineered and manufactured with great precision, this range of components from APS represents many years of research and development and is arguably the ultimate in high horsepower turbocharging for the Subaru WRX/STI.
