Give your Fiesta ST the airflow it deserves. The Mishimoto Fiesta ST intake cranks the power up by 6 whp and 10 wtq while running on the stock tune. The mandrel bent aluminum piping allows for smooth, uninterrupted airflow straight to the turbo inlet hose and into the turbo. The Fiesta ST intake pipe also features a CNC machined MAF housing that uses the stock MAF sensor, and it includes two CCV ports with a silicone PCV adapter. The piping is available with either a polished, wrinkle black, or wrinkle red finish to maximize engine bay aesthetics. This Fiesta ST intake also features a black powder coated airbox to keep the air filter isolated from unwanted engine bay heat. This will help keep your air charge nice and cool, and, like all Mishimoto Fiesta ST parts, this intake comes with the unbeatable Mishimoto Lifetime Warranty!
