The Cold Air Intake System produces Horsepower and Torque gains by replacing your vehicle’s restrictive factory air filter and air intake housing. This air intake system was designed, tuned and dyno-tested to fit specific Honda Civic models. Air enters the system through an oversized AEM Dryflow synthetic washable air filter for outstanding air flow, filtration and performance. The air filter is placed into the original air box space and is protected by a heat shield which is designed to reduce intake air temperature and increase Horsepower. This air intake system was developed to accommodate the engine’s factory emissions control devices. The tapered cylinder shaped AEM Dryflow air filter is made from an oil-free, synthetic filter media that can be used for up to 100,000 Miles before cleaning is needed.
