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.
And, it's easy to install with no cutting or drilling required. It's what APS use on their 540hp WRX race car. APSWRX-HFA Fits MY97, MY98, MY99, MY00, STI 2 Door Version 5, STI 4 Door Version 6 NOTICE: This system was designed to be used with a properly tuned engine management system. Installation of intake without an ecu properly tuned on your vehicle may result in less than optimal results. |
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.
