APS High Flow Cold Air Intake
The APS smooth bore cast aluminium cold air intake system and air filter delivers a huge volume of cold air to the turbo charger for maximum engine performance. 

This APS cold air intake system is certainly the most cost effective way to achieve greater air flow, great looks and fantastic sound for your sedan or wagon.

Unlike ram pods which source hot air from under the bonnet, the APS system breathes cool air from the inner guard for the optimum engine performance and durability. More importantly the air through the APS high flow air intake system is consistent in temperature. This means that the engine management unit's temperature compensation system operates correctly - unlike devices that source air from the highly turbulent areas under bonnet. 

And, it's easy to install with no cutting or drilling required.  

WRX and STI enthusiasts (sedan and wagon) will be delighted to know that the APS High Flow Air Intake system has been designed as a do-it-yourself installation - and we are sure you will find the experience personally rewarding.

NOTICE: APS manufactures the APS High Flow Cold Air Intake system in 2 sizes.

  • APSWRX-HFA/01 - 65mm internal bore diameter near the Air Flow Sensor in order to maintain stock Air Flow Sensor operation and to work in harmony with the stock engine management.
  • APSWRX-HFA/02 - 70mm internal bore diameter around the Air Flow Sensor in order to support extreme levels of horsepower without overwhelming the stock Air Flow Sensor. Note that this option requires additional engine tuning.

Now everyone can experience the benefits of the world's most advanced cold air intake to suit the MY01 model onwards WRX and STI.
