The Injen SP1209P short-ram intake for 2015–2021 Subaru WRX 2.0L uses a mandrel-bent 3.00" 6061-T6 aluminum tube, application-specific heatshield, and a SuperNano-Web dry filter to improve airflow and under-hood appearance. MR technology at the MAF helps preserve stock fueling without check-engine lights; dyno-proven gains reach about 24 hp and 20 lb-ft. Note: not currently CARB exempt for California purchase or registration.
