Description

The Mishimoto MMAI-WRX-15BP Polished Cold Air Intake is engineered to significantly increase power, improve airflow, and enhance turbocharger sound for the 2015–2021 Subaru WRX. Featuring a free-flowing intake design, reinforced silicone induction hoses, and an optional enclosed airbox, this system replaces the restrictive factory intake for noticeable gains in horsepower, torque, and responsiveness.

Dyno results show maximum increases of up to 33 whp and 30 wtq on the stock tune, with peak gains of 28 whp and 21 wtq. With proper tuning and 93-octane fuel, this intake is capable of gains up to 70 whp and 70 wtq while maintaining safe air-fuel ratios, making it one of the most impactful bolt-on upgrades for the FA20DIT platform.

The polished aluminum intake piping is paired with a wire-reinforced silicone lower induction hose designed to prevent collapse under suction and boost. The high-flow oiled air filter offers increased filtration surface area over stock and is fully serviceable for lifetime use. The included airbox helps reduce heat-soak while maintaining a clean, OEM-like engine bay appearance.

This intake produces an aggressive turbo spool sound, pronounced BPV noise, and a stronger induction tone under load. Designed in Delaware, made in the USA, and backed by Mishimoto’s Lifetime Warranty, this system offers top-tier performance and reliability.
