Injen SP1208WR SP Series Wrinkle Red Short Ram Intake, Subaru WRX STI 2.5L Turbo 2018-2021

Description

Give your Subaru WRX STI more usable power with the Injen SP1208WR SP Series short ram intake. Injen dyno testing shows gains of up to 26 horsepower and 24 lb-ft of torque. Designed as a bolt-on replacement for the factory intake, it delivers better airflow and throttle response with no additional tuning required.

At the heart of every SP Series intake is Injen's tuned-intake engineering. The 6061-T6 aluminum tube used on the Subaru WRX STI is designed to reduce restriction and turbulence, and Injen validates each design on the dyno so power increases arrive without compromising air/fuel ratios. This kit incorporates Injen's patented MegaRam (MR) Technology to help maintain safe air/fuel ratios while maximizing gains.

Every kit includes an Injen SuperNano-Web dry filter. The synthetic nano-fiber media traps fine dust without oil and flows a large volume of air, making it well suited to daily driving in the Subaru WRX STI. When service is due, order Injen replacement filter part number X-1059-BB. An optional Injen Hydroshield pre-filter (1040BLK) is available for added protection from water and debris.

The textured wrinkle red powder-coat finish adds a bold splash of color under the hood. Expect a noticeably more aggressive intake sound when you get on the throttle. Installation is straightforward on the Subaru WRX STI, and every system is backed by the Injen Technology Limited Lifetime Warranty.
