The AEM Cold Air Intake System is the result of extensive development on a wide variety of cars. It is the most advanced Cold Air Intake System on the market. Each system is specifically engineered for its application. All AEM Cold Air Intake Systems deliver maximum performance gains through lightweight, all-aluminum, mandrel-bent tubing that is tuned in both length and diameter. The aluminum will not crack in extended use like plastic. The tube length and diameter are matched for each specific engine to give power over a broad RPM range. Unlike plastic systems that use a continually diverging cross-section, we take advantage of the acoustical energy in the inlet duct to promote cylinder filling during the intake valve-opening event. Every intake is coated with a high-gloss, heat-reducing Zirconia based powder coating.

The AEM V2 intake system features a revolutionary breakthrough in inlet system design that delivers maximum power throughout the entire powerband of the engine. AEM has always designed its air intake systems to deliver maximum torque and power in the engine’s lower-rpm region because that is where most daily driving occurs. This creates a compromise because the operating frequency of the pipe is fixed, and does not change with rpm, causing the sound wave to be ineffectual when it is not in sync with engine speed.

The AEM Cold Air System is the result of extensive development on a wide variety of cars.
Each system is engineered for the particular application. The AEM Cold Air System differs from
all others in several ways. We take the inlet air from outside of the engine compartment where
the inlet air is considerably cooler than the hot under hood air. The cooler inlet air temperature
translates to more power during the combustion process because cool air is denser than warm
air. AEM has conducted extensive inlet air temperature studies and we have seen temperature
reductions of up to 50 degrees by pulling air from outside of the engine compartment. The air
mass flow to the engine is increased because of the increased airflow and reduced inlet
temperature, which translates to more power. The AEM Cold Air Systems come with complete
instructions for ease of installation.
