Description
The Mishimoto MMAI-WRX-15BWRD is a performance air intake engineered specifically for the 2015+ Subaru WRX, finished in an aggressive wrinkle red on its aluminum intake piping. Its standout feature is a wire-reinforced lower induction hose that resists collapsing under suction and boost, paired with a high-flow, reusable Mishimoto oiled air filter that offers more filtration surface area than the stock paper element.
As a cold air intake designed to replace the restrictive factory air intake system, this kit uses the stock intake duct to feed cool, dense air directly to the intake filter. On dyno testing, Mishimoto recorded maximum gains of up to 33 whp and 30 wtq and peak gains of up to 28 whp and 21 wtq while maintaining safe air/fuel ratios on the stock tune; with a tune and 93 octane fuel, gains of up to 70 whp and 70 wtq were recorded on a 6-speed WRX. Beyond output, the free-flowing design of this air intake filter setup produces a noticeably aggressive tone under acceleration and boost and amplifies turbocharger spool and blow-off valve sounds. It’s a complete bolt-on cold air intake that functions with the stock tune, installs in about one hour with common hand tools, and is optionally available with an enclosed airbox that maintains a stock-like engine bay appearance while shielding the filter from engine bay heat-soak.

Frequently Asked Questions
What Subaru WRX years and trims does this intake fit?
This Mishimoto air intake is a direct fit for the 2015-2021 Subaru WRX (non-STI, chassis code VA, FA20DIT engine), covering the Base, Limited, and Premium trims (2015-2021), Sport and Sport-tech trims (2017-2021), 6-speed manual and CVT models (2018-2021), Sport-tech RS (2019-2020), Raui Edition (2019), and EyeSight trim (2021).
Does this intake work with the factory tune?
Yes, this is a complete bolt-on intake that functions perfectly with the stock tune and was dyno tested to maintain safe AFRs on the stock tune.
How much power can this intake add?
Dyno testing showed maximum gains of up to 33 whp and 30 wtq and peak gains of up to 28 whp and 21 wtq on the stock tune, while gains of up to 70 whp and 70 wtq were recorded with a tune and intake using 93 octane fuel on a 6-speed WRX.
What does this cold air intake system do?
It replaces the restrictive factory intake with free-flowing aluminum piping and a wire-reinforced hose that resists collapsing under suction and boost, while using the stock intake duct to deliver cool air to a high-flow, reusable oiled filter, increasing filtration surface area and amplifying turbocharger spool and blow-off valve sounds.
How often should the air filter be cleaned?
Mishimoto recommends cleaning and re-oiling the oiled air filter every 10,000–15,000 miles during normal driving, and inspecting or servicing it more frequently if you drive often in dusty or off-road conditions. Filter re-oil is not included in the Lifetime Warranty.
What is included in the kit?
The kit includes two aluminum intake pipes, one 90-degree silicone upper hose, one silicone lower hose, one high-flow oiled filter, an airbox with protective edging, and the Mishimoto Lifetime Warranty.
