The DC Sports Short Ram Intake System for your 02-07 Subaru Impreza WRX/STI is designed to increase performance and improve throttle response, all while remaining 50 State C.A.R.B compliant. We replace your restrictive, brittle, OEM rubber intake pipe with smooth mandrel-bent aluminum tubing and pair it with a DC Sports high flow, performance air filter. This allows for increased airflow, cooler air ingestion, and reduced intake air temps. You can install our kit with the comfort of knowing your intake system will meet emissions standards anywhere in the USA. Every DC Sports intake kit comes with all the needed hardware for installation and requires absolutely no modification or cutting.
Included:
Multi-Ply Hight Temp Silicone Couplers
Washable and Reusable High Flow, Performance Air Filter
Lightweight Aluminum Tubing
