The Injen RD1425BLK is a Race Division cold air intake built for the 1997-2001 Acura Integra Type R with the 1.8L four-cylinder. Its intake tube is mandrel-bent 6061-T6 aluminum with TIG-welded construction, and it feeds a fully serviceable SuperNano-Web dry air filter. The wrinkle black finish is the powder-coated option in the RD line.
Compared with the stock airbox, this kit is engineered to add power while keeping air-fuel ratios in a safe range, so most buyers can skip the cost of a dedicated tune. The manufacturer describes it as a drop-in part designed to avoid an expensive tune, and it lists the system as dyno-proven. Choosing it over a cheap no-name tube makes sense for buyers who want the premium welded construction and a filter that can be cleaned and reused. Search terms that fit this part include Integra Type R 1.8L cold air intake no tune, RD1425BLK wrinkle black CAI, and Integra Type R SuperNano-Web intake.
The manufacturer states the intake provides power gains while maintaining air-fuel ratios with no additional tuning.
The manufacturer lists replacement air filter part number X-1014-BB. The stock-style SuperNano-Web filter is described as fully serviceable, so it is designed to be cleaned and reused; follow the manufacturer's care guidance for cleaning.
Yes. The manufacturer offers an optional hydroshield, part number 1033BLK in black or 1033RED in red, to help keep water out of the intake.
The manufacturer's install sheet describes this as a job that requires mechanical skill, and Injen strongly recommends professional installation. Start by loosening the clamps at the airbox and throttle body, then release the airbox lid latches and remove the stock airbox and duct. Position the new tube, insert the filter end into the resonator opening, and secure the mounting point with the 6mm flange nut and fender washer before tightening all clamps. The manufacturer also warns against installing the intake while the engine is hot, so let the engine cool first.
