Cold Air Intake System
The AEM 21-5004C Performance Hybrid Cold Air Intake System produces horsepower and torque gains by replacing your vehicle’s existing restrictive air filter and air intake assembly. This air intake system was designed, tuned and dyno-tested to fit specific Honda Civic models with a H22A engine swap. Air enters the system through an oversized AEM Dryflow synthetic washable air filter for outstanding air flow, filtration and performance. The air filter is installed in 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 emissions control devices including a replacement engine breather 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. Since the hybrid air intake is for a vehicle with an engine swap, this air intake cannot be sold in California. It is not legal for use in California or other states adopting California emission standards.
