This 02-05 Subaru WRX AEM Cold Air Intake System relocates the filter outside of the engine compartment to deliver cool air inlet temperatures. Cooler air carries more oxygen, which translates into a more intense explosion in the combustion chamber to create more horsepower and torque. AEM also tunes the inlet pipe in length and diameter to match the engine's resonance and help move more air to the cylinders, thus delivering larger power gains.
**This intake will not work with a front-mount intercooler
