K&N Adds 12 horsepower to the Already Impressive WRX STi with their Typhoon Air Intake System

RIVERSIDE, CA, -- The leader in High-Flow Air Filters and Intake Kits for decades, K&N Engineering recently put the finishing touches on their Typhoon® Intake Kit for the 2000 to 2007 Subaru Impreza WRX and WRX STi (PN# 69-8001TWR).

Engineered on K&N's in-house dyno, the newest Typhoon® kit boasts a number of unique features, including a "grivory" velocity stack for improved airflow, a special insulated shield to protect intake tube from heat (this is in addition to the powdercoated heat shield that keeps hot air from the air filter). Testing showed estimated gains of 12 horsepower at 5050 rpm on a stock (unmodified) 2004 STi.

Like all K&N Typhoon® Intake Kits, the WRX STi kit is constructed of mandrel-bent 6061, aluminum tubing (2-3/4-inch tubing is used on the STi kit) and includes a CNC-machined, billet mass airflow sensor (MAS) adapter. Unlike other K&N 69-Series Typhoon® High-Flow Intakes, this system features an STi exclusive, wrinkle red powder-coat finish to match the car's factory intake.

The heart of each Typhoon Intake Kit is a genuine K&N High-Flow Air Filter, made of four layers of high quality cotton gauze, sandwiched between epoxy-coated aluminum wire mesh and treated with a specially-formulated oil to trap and hold dirt and debris. For the WRX STi application the filter is dressed up with a real carbon fiber top from K&N's in-house composites shop. All K&N filters are washable and re-usable with K&N's Recharger® Kit (sold separately), and are covered by the famous K&N Million Mile Limited Warranty®.
