The K&N 69-6501TB Typhoon cold-air intake system is a free-flowing, mandrel-bent aluminum tube air induction system designed to fit some Mitsubishi Eclipse models. 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 69-6501TB cold-air intake consists of a K&N high-flow air filter that mounts between the driver side wheel well and from bumper. Cooler outside air is directed through free-flowing aluminum tubing into a short ram induction tube that delivers high volumes of clean, colder air into the engine's throttle body for a guaranteed power gain. 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 100,000 miles before servicing is needed depending on driving conditions. This cold air intake is relatively easy to install usually in 90 minutes or less. Some Typhoon air intakes are not legal for sale or use in California or other states adopting California emission standards while others are CARB exempt and 50 state legal. Check the applications and specific CARB status for each vehicle and air intake.
