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.

4Good experince
By P. Easley-Correa
I had to replace a broken Original intake, the cost was quite expensive, so I choose to upgrade to a cold air intake system instead, it was about the same money anyway. My choice to try the AEM was due to their reputation and other users comments. It has been 5 months, and I am very happy with my intake.I have not seen any improvement in MPG, and not a hugh difference in accelleration either, but in does not choke or spudder ever, and was pretty easy to install.Ford Focus 02 ZTS auto

Product Description

AEM’s V2 intake systems use a patented dual chamber design that maximizes horsepower and torque - producing even more power that our own Cold Air systems. On a dyno graph, the area under the power band (or power curve) represents the amount of effort that an engine is producing. The larger the overall area under the curve, the more power your engine is making. The AEM V2 utilizes a dual chamber (using two different diameters and lengths of piping) that creates multiple frequency sound waves to produce the largest area under the curve of any intake system on the market. These sound waves help charge the cylinders with more air throughout the entire rpm range and are what enables the V2 to outperform even our own Cold Air systems. We have found that inlet length plays a vital role in the power production of V2 systems and not all V2 induction systems relocate the filter outside of the engine compartment. In these cases, we performed extensive temperature testing to locate the filter in the coolest area of the engine compartment to achieve the lowest inlet temperatures possible. Please refer to our temperature testing procedures for more information.

Product Description

AEM Short Ram intake systems are an economical alternative to our Cold Air systems and deliver performance, value and ease of installation over any other short inlet intake. Our Short Ram intakes install easily under the hood and cost less because we use less material to manufacture them. During the development process, we found certain applications respond favorably to shorter inlet lengths over our longer Cold Air designs. For these applications (denoted in the search results page), we offer a Short Ram system only. We perform extensive temperature testing to locate the filter in the coolest area of the engine compartment, which allows our Short Ram systems to achieve the lowest inlet temperatures possible. Please refer to our temperature testing procedures for more information.

5Vtec
By musoman
I installed this intake in my 2001 honda accord vtec. It sounds amazing I have no exhaust so all you hear is vtec. Sounds way better than cheap ebay intakes. Spending a little bit more is worth it. Sounds great looks great and is easy to install.
