Mishimoto MMAI-STI-15WBK Performance Cold-Air Intake Wrinkle Black

The Mishimoto MMAI-STI-15WBK is a dyno-proven performance cold-air intake engineered as a direct-fit replacement for the restrictive stock airbox. Delivering up to 20+ wheel horsepower and 18 lb-ft of wheel torque over the stock intake while maintaining safe air/fuel ratios, this intake is an ideal bolt-on upgrade for street driving or autocross use.

The mandrel-bent aluminum intake pipe features a wrinkle black powder-coat finish and integrates a CNC-machined mass airflow sensor (MAF) housing along with Mishimoto's air straightener technology to deliver accurate, consistent MAF readings for a smooth power band. A powder-coated heat shield positions the air filter outside the hot engine bay to minimize intake air temperatures (IATs) and prevent heat soak.

The included Mishimoto oiled air filter offers 16% greater surface area than the stock unit for optimal airflow and superior filtration of dirt and debris. The filter is fully serviceable and reusable, providing a lifetime of reliable performance. A rubber cap is supplied to cover the sound symposer (noise generator) housing. This intake also delivers an aggressive, rich induction tone under acceleration — a noticeable improvement over the stock system.
