The K&N 69-1504TR Typhoon air intake system is a free-flowing, mandrel-bent aluminum tube air induction system designed to fit specific Honda Civic Si 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. Included is 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 an attractive red powder-coated intake tube into the engine's throttle body for a guaranteed power gain. The oversized cone shaped air filter can be used for up to 100,000 miles before servicing is needed depending on driving conditions. This air intake is relatively easy to install usually in 90 minutes or less using existing factory mounting points. The tools needed are a screwdriver, ratchet set and several wrenches.

K&N's replacement air filters are designed to increase horsepower and acceleration while providing excellent filtration. We make over 1,200 different replacement air filters for the majority of vehicles on the road. These filters are washable and reusable and are custom designed to fit into your existing factory air box. Their drop-in design means adding performance is simple. With most vehicles you simply remove the disposable air filter and replace it with a K&N. See applicable instruction sheet for details. Our stock replacement air filters for street vehicles are covered by our famous K&N Million-Mile Limited Warranty and will be the last air filter your vehicle will ever need.
