Cold Air Intake System

The Injen RD1500BLK is a performance cold air intake (CAI) system engineered to deliver significant bolt-on horsepower gains while enhancing the visual appeal of your engine bay. Its core component is a precisely mandrel-bent 6061-T6 aluminum air intake tube, which ensures an uninterrupted path for optimal airflow, drawing in the coolest, densest air available. This system incorporates a fully serviceable Injen SuperNano-Web dry air filter, constructed from synthetic materials. This filter design maximizes surface area for greater airflow and provides superior filtration. The Injen RD intake is tuned to maintain safe air-fuel ratios across the powerband, eliminating the need for additional tuning. Beyond performance, it produces an aggressive and distinctive exhaust note. The RD1500BLK is specifically designed as a direct fit for the 1988-1991 Honda Civic EX and SI models equipped with the L4-1.6L engine. It also carries a CARB EO number (D-476-3), indicating compliance with California Air Resources Board emissions standards. The intake system comes with Injen Technology's limited Lifetime Warranty.
