AEM 88-91 Civic EX/SI CRX SI Polished Short Ram Intake

The AEM 22-400P Performance Short Ram Air Intake System has been engineered to be an affordable and easy way to boost the horsepower and torque of your engine. The restrictive factory air filter and air intake housing are replaced with this AEM air intake system which was designed, tuned and dyno-tested to fit specific Honda Civic and CRX models. Air enters the system through an oversized AEM Dryflow synthetic washable air filter for outstanding air flow, filtration and performance. The sound your engine makes when accelerating is also modified to a fuller, more aggressive resonance allowing you to hear and feel the horsepower upgrade. The intake tubing is constructed from mandrel-bent aluminum featuring a durable chrome-like finish. This air intake system was developed to accommodate the engine's factory emissions control devices including the IAT sensor, PCV breather pipe and vacuum lines (where equipped). 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 easy to install with commonly available tools and it 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.

AEM's Performance Short Ram Air Intake System gives you more power and acceleration by replacing the restrictive factory air filter and air intake assembly. The intake tube has an attractive yet durable powder-coated finish. Fitment: Honda Civic EX 1990 to 1991 Honda Civic RT 4WD 1989 to 1991 Honda Civic Si 1989 to 1991 Honda CRX Si 1988 to 1991
