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.

The product was great. it was delivered on time and it fit my 06' nissan perfectly. The only thing that can say is to please pay close attention to the description and make a visual in your head by what the description says. Dont go by the pictures cause sometimes they can be inaccurate.The description said polished cold air intake system. Although the picture showed the item being white, I thought in my head that it was going to be a mixture of both (Polished and white). Because i thought that the product was going to be white, i was a little let down when i opened the box and saw that it was a metal polished item. But i took full responsibility to my actions of not paying more attentions to the description, so im still giving the product a 5 star cause it does what it supposed to do and it sounds great :)thinking that the product was going to be white when it clearly said polished is a total user error. so please pay more attention to descriptions and not just the pictures when buying because it helps a lot!
