1999 BMW 325xi Cold Air Intake System at Tuners Depot
The AEM 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. The AEM 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. The AEM Cold Air systems are dyno-proven. Every AEM Cold Air induction system features the highest standards of construction and they are so confident in their fitment and performance that they 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.
