The stock intake duct is utilized to provide cool airflow to the high-flow Mishimoto oiled air filter, which features increased filtration surface area compared to the stock paper filter. This filter can be cleaned and reused, providing a lifetime of service. The intake is optionally available with an enclosed airbox for protection against engine bay heat-soak, and it provides a stock-like engine bay appearance as well. This unit is a complete bolt-on that functions perfectly with the stock tune and can be installed in one hour using common hand tools.
Mishimoto does not recommend using intake with 91 octane fuel and no tune. Mishimoto recommends purchasing the ECUtek tuning kit if you live in an area where only 91 octane is available. Using the intake with 91 octane and no tune may damage your engine.
