An AEM cold air intake delivers the coldest air possible thanks to the innovative design. They’ve repositioned the filter to sit outside the engine compartment to reduce the possibility of heat build-up. Cold air is more effective than hot air because it is denser, which allows more oxygen to flow through your system in the same amount of space. This allows for improved fuel combustion for incredible power. Give yourself the added performance you crave with the help of an AEM Cold Air Intake.
