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 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. But thats only part of the power equation. Tuning the inlet pipe in length and diameter to match the engines resonance helps move more air to the cylinders (think of your engine as a big air pump), and this tuning allows us to deliver large power gains. 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.

Every AEM cold air induction system features high 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 include a lifetime DRYFLOW synthetic air filter and come with a limited lifetime warranty.

4 Star Rating Great but ... by Lamont B
Loved this on my 1991 accord , there was deffinately a change in the engine sound and it did get a lil peppier after I installed. For this price a 2 piece setup would work better with a relief valve incase you run thru a puddle. Sadly because its a one piece, during a huge rain storm I ran thru a puddle and sucked water into my engine ...killing my engine. If you use make sure you get relief valve so that on rainy days you dont have to worry about sucking water into your engine.
