K&N 69 Series Typhoon Air Intake KitsFits 2018-2019 Subaru WRX 2.0L - KN69-8011TTKBrand: K&NPart Number: KN69-8011TTKDescription: The K&N Typhoon air intake system is a free-flowing, mandrel-bent aluminum tube airinduction system. The restrictive factory air filterand 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 engin's RPM range. In addition to more power, this air intake system improves engine sound with more aggressive and deeper acoustics during acceleration.The air intake comes with a black rubber topped K&N high-flow air filter and a heat shield that installs intothe 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 textured black powder-coated finish that's made to last and it accommodates the factory mass air sensor. The oversized coneshaped air filter can be used for up to 100,000 miles beforeservicing is needed depending on driving conditions. This air intake is relatively easy to install usually in 90 minutes or less using existingfactory mounting points. The tools needed are a couple of screwdrivers, a ratchet set and some wrenches
