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

Originally developed to enhance the Version 5 STI, this APS cold air intake system is certainly the most cost effective way to achieve greater air flow, great looks and fantastic sound. 

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.
