The Injen IS short ram intake for 1989–1990 Nissan 240SX (2.4L) swaps the factory airbox for mandrel-bent aluminum tubing and a SuperNano-Web dry filter to improve airflow and throttle response. The kit offers dyno-proven gains, is available polished or black, maintains safe air-fuel ratios without extra tuning, includes tubing, filter and hardware, and carries Injen’s limited lifetime warranty; not CARB exempt for California in some SKUs.
