Check Vehicle Fit

The AEM 21-403C Performance 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 Acura Integra 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 relocated to the passenger-side wheel well which is designed to reduce intake air temperature and increase horsepower. The intake tubing is constructed from mandrel-bent aluminum featuring a durable gunmetal gray powder coated finish. This air intake system was developed to accommodate the engine’s factory emissions control devices including a replacement engine breather hose and water bypass hose. 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 (depending on driving conditions). The air intake system is backed by AEM's Lifetime Limited Warranty. Some AEM air intakes are not legal for sale or use in California and other states adopting California emission standards, while others are 50 state legal. View the 21-403C vehicle applications to determine the legal status for each vehicle.

    Comments about AEM Induction Cold Air Intake System:

    It took me about two hours to remove my old air intake and install this baby. It did require removing the front wheel but if you have a decently outfitted garage it should not be a problem. The CAI takes up much less room and looks very nice with its polished finish under the hood. It delivers on better performance and a nicer, throatier sound from the engine.
