FIPK Air Intake System

The K&N 57-3503 FIPK (Fuel Injection Performance Kit) air intake system is designed to replace the restrictive stock air filter and intake housing in compatible 1988-1991 Honda Civic and CRX models. By smoothing and straightening airflow, this system dramatically reduces intake restriction, enabling your engine to ingest a larger volume of air. This increased airflow translates directly into more power and improved acceleration throughout the entire RPM range. At the heart of the 57-3503 is K&N's signature high-flow air filter, featuring a chrome top and a screw thread for secure installation into the original air box space. The oversized, tapered cylinder air filter is built for longevity, requiring service only after up to 100,000 miles of driving, depending on conditions. Installation is designed to be straightforward, typically completed within 90 minutes or less using common hand tools and existing factory mounting points. K&N backs this performance upgrade with a Million Mile Limited Warranty, underscoring its commitment to quality and durability. This air intake system is street legal in all 50 US states. This K&N 57-3503 intake system is specifically designed to fit the following vehicles: 1988-1991 Honda Civic (Base, DX, EX, LX, RT 4WD, Si, Wagovan) and 1988-1991 Honda CRX (Base, DX, Si). It is also noted to fit 1988-1991 Honda Civic FWD/4WD and 1988-1991 Honda CRX FWD models.
