The Injen RD Series Performance cold air intake is a bolt-on kit for the 1997-2001 Honda Prelude L4 2.2L. The manufacturer builds it from mandrel-bent 6061-T6 aluminum tubing with TIG-welded construction and pairs it with a fully serviceable Injen SuperNano-Web dry air filter. The tube sits behind the front bumper to draw cooler, denser air than the stock airbox, and Injen states the kit adds power while keeping air-fuel ratios safe with no additional tuning. Compared with a cheaper universal intake, this kit is engineered to the Prelude's airflow, comes with a reusable filter, and carries the manufacturer's limited lifetime warranty.

Expect real labor for this install. The manufacturer's install sheet calls for mechanical skill and notes that the front bumper, air resonator box, battery, and battery tray must come out, and that the plastic plugs and screws holding the bumper can be stubborn. The sheet also covers removing the vacuum solenoid, vacuum tank, and vacuum hose, then capping the 5mm intake manifold port. Injen strongly recommends professional installation. Owners on user forums say the lower intake half and filter fit where the resonator box was once the bumper is off.

The manufacturer states that the RD intake provides power gains while maintaining A/F ratios with no additional tuning.
The manufacturer lists replacement air filter part number X-1013-BB. The included SuperNano-Web dry filter is fully serviceable, so it can be cleaned and reused.
The manufacturer lists CARB EO number D-476-3 for this part. Confirm the number against the manufacturer's documentation if your state inspection requires it.
Per the manufacturer's install sheet, this is a moderate-difficulty job that requires mechanical skill, and Injen strongly recommends professional installation. Plan on removing the front bumper, air resonator box, battery, and battery tray, and budget extra time for the plastic bumper plugs and screws. Disconnect the vacuum solenoid, vacuum tank, and related hoses, then cap the 5mm intake manifold port as the sheet directs. Owners on user forums note that the lower intake half and filter mount where the resonator box sat, and that the stock vacuum lines simply move over to the new intake.
