Product Description
AEM pioneered the Cold Air induction system for sport compact cars in 1994. A Cold Air intake system relocates the filter outside of the engine compartment to deliver the coolest air inlet temperatures possible. Cooler air carries more oxygen, which translates into a more intense explosion in the combustion chamber to create more horsepower and torque. But that's only part of the power equation. Tuning the inlet pipe in length and diameter to match the engine's resonance helps move more air to the cylinders (think of your engine as a big air pump), and this tuning allows us to deliver the maximum power gains throughout the entire RPM range. We also monitor fuel trim correction factors and all OBDII sensors during R&D to eliminate leaning the engine out and/or throwing a check engine light. Our Cold Air systems are dyno-proven and tested against the competition with the goal of creating more useable power than any other system of their kind. Every AEM Cold Air induction system features the highest standards of construction and we are so confident in their fit and performance that we guarantee them for the life of your vehicle. All AEM Cold Air systems are either 50-state legal or pending (excluding "Off Road" and "Hybrid" systems), include a lifetime DRYFLOW Synthetic air filter and come with a limited lifetime warranty.

I researched CAI (cold air intakes) atleast 2 to 3 weeks before I decided with AEM. I was inpressed with the shipping via Amazon, but further more the quality of AEM was just top notch. My other choice was Injen, but since I could not find enough backing info to choose them over AEM. To back my choice I research sound on utube and other web forums. Sound quality is pretty deep and low end torque is very on point. I can't tell about HP gain, but I bet its there somewhere. The stock setup in a eclipse 4 banger is horrible. Good luck to all that read this and remember if your driving in heavy water areas you should get a bypass to save your engine. My ride is a spring/summer/fall and never sees rain nor snow. visit my ride @ http://www.cardomain.com/ride/3014140
