Injen SP1208WB SP Series Wrinkle Black Short Ram Intake, Subaru WRX STI 2.5L Turbo 2018-2021

Description

The Injen SP1208WB SP Series short ram intake is a direct-fit performance upgrade for the Subaru WRX STI. Injen dyno testing shows gains of up to 26 horsepower and 24 lb-ft of torque. It replaces the restrictive factory intake with a less restrictive design that improves throttle response and works with the stock engine calibration.

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.

Filtration is handled by Injen's SuperNano-Web dry air filter, a synthetic, fully serviceable element that captures fine particles while providing a large surface area for airflow. No oiling is required, which keeps sensors on the Subaru WRX STI clean. 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 black powder-coat finish resists heat and blends into the engine bay. The system provides a deeper, more aggressive intake tone under full throttle and installs with basic hand tools. Injen designs and manufactures its intakes in Pomona, California, and backs them with a Limited Lifetime Warranty.
