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.

Installation could be more streamlined
By Jon
I am an auto technician and have dealt with many air intakes. This system may be a great power addition (although not felt by me) but the installation process required removal of the left front tire and the fender liner. So every 5,000 miles when the filter needs to be cleaned, that process will have to be duplicated. I thought that was a little bit much considering there wasn't much of a power addition to the engine. As far as quality, I believe this to be on par with most aftermarktet intakes. It ships with all new band clamps and silicone sleeves for hookup.
