| AEM intake systems are possibly one of the most advanced and efficient intakes today. They are guaranteed and to maximize your A4's ability to breath deeply and perform under any type of extreme conditions. AEM Intake Systems are designed to produce massive horsepower and torque gains as well as better engine sound when used as a replacement for the factory airbox and air filter. AEM intake systems are designed, tuned, and dyno-tested to fit specific cars and trucks, and include an oversized AEM Dryflow synthetic washable air filter for optimum air flow, filtration, and performance while allowing easy oil-free cleaning. AEM creates these intake systems using mandrel-bent aluminum intake tubes, powder coated heat shields, and high quality hardware designed to reduce restriction and reduce intake temperature.
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 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 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 AEM are is confident in their fit and performance that AEM 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.
