Mishimoto Cold Air Intake Red 2015-2017 STI

Unlock extra horsepower and torque for your 2015-2017 Subaru STI with the Mishimoto Performance Air Intake. Engineered specifically for your STI, this kit replaces the restrictive stock airbox with a fully optimized system designed to improve airflow, reduce intake temperatures, and deliver a more aggressive engine tone.

Performance You Can Feel
Dyno-tested and proven, this intake provides up to 20 whp and 18 wtq gains while maintaining safe air/fuel ratios—perfect for street driving or autocross performance. The mandrel-bent aluminum intake pipe is available in polished aluminum, wrinkle black, or wrinkle red, paired with a Mishimoto air straightener and CNC-machined MAF housing to ensure precise airflow and consistent MAF readings, translating to smooth, reliable power throughout the RPM range.

Optimized for Cooler Air
To reduce intake air temperatures (IATs), the Mishimoto air filter is positioned outside the hot engine bay. The included powder-coated heat shield protects against heat soak, while the high-flow oiled air filter provides 16% greater filtration surface area for maximum airflow and proper debris filtration. The filter is fully serviceable, offering a lifetime of reliable performance.

Complete, Easy Installation
This intake comes with all necessary hardware, including a silicone coupler, clamps, and a rubber cap for the sound symposer housing, for a seamless bolt-on installation in under one hour.

Aggressive Sound, Aggressive Performance
Along with power gains, the Mishimoto STI Air Intake delivers a richer, more aggressive intake tone that significantly enhances the driving experience over the stock system.
