The Mishimoto Cold Air Intake stacks up as one of the better first line of modifications you can add to your 2015+ STI. This kit has been engineered specifically for the 2015 STI, and it includes everything needed to replace the factory restrictive stock airbox.
Mishimoto’s engineers have spent months refining this design in an attempt to gain every last bit of performance out of an aftermarket cold air intake. This dyno proven design gains an additional 20 WHP and 28 WTQ over the stock intake while maintaining safe air/fuel ratios.
Included in these kits is a powder-coated black or red mandrel bent aluminum intake pipe. Polished is also an option, however in this case we have a red pipe. These pipes utilize a CNC-machined mass airflow sensor housing to provide accurate and consistent MAF readings, which translates into a smooth power band.
To help with reduced intake temperatures, this intake was designed to be located outside of the hot engine bay, and a powder-coated heat shield prevents any heat-soak from happening.
Mishimoto’s free-flowing air filter provides a 16% greater surface area, optimal airflow, and proper filtration of dirt and debris. This filter comes pre-oiled, and it is completely serviceable allowing for a lifetime of reliable use. To top off this cold air intake, a rubber cap is included to place over the sound symposer housing. After installation enjoy the additional aggressive, and rich intake tone that is a huge improvement over the stock intake.
