The restrictive factory air filter and air intake housing are replaced by the K&N Typhoon cold-air intake which is designed to pull in relatively cooler air and dramatically reduce air flow restriction by smoothing and straightening air flow. This allows your engine to inhale a larger amount of denser air than the factory air intake. More air means more usable power and acceleration throughout the engine's RPM range. The cold-air intake system accommodates the factory mass air sensor and air pump vent hose. The oversized cone shaped air filter comes with a water repellent DryCharger filter wrap to protect the filter from moisture. The air filter can be used for up to 160,000km 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.
