K&N 2018 Subaru WRX STI H4-2.5L F/I Typhoon Performance Intake 69-8009TWR
The K&N 69-8009TWR Typhoon air intake system is a free-flowing, mandrel-bent aluminum tube air induction system designed to fit some Subaru WRX STI Turbo models. The restrictive factory air filter and air intake housing are replaced by the K&N Typhoon air intake which is designed to dramatically reduce air flow restriction as it smoothes and straightens air flow. This allows your engine to inhale a larger amount of air than the factory air intake. More air means more usable power and acceleration throughout the engine's RPM range. In addition to more power, this air intake system improves engine sound with more aggressive and deeper acoustics during acceleration. The 69-8009TWR air intake comes with a black rubber topped K&N high-flow air filter and a heat shield that installs into the original air box space. Air is directed through the intake tube into the engine's turbo inlet for a guaranteed power gain. The intake tube has an attractive red textured powder-coated finish
