Cold Air Intake Polished w/ Air Box

• 2015–2021 Subaru | WRX

Mishimoto has developed a performance air intake engineered specifically for the 2015-2021 Subaru WRX (FA20DIT, VA chassis). The kit features polished mandrel-bent aluminum intake pipes and an enclosed airbox that retains a stock-like engine bay appearance while protecting against heat soak. The stock intake duct is utilized to supply cold air to the high-flow oiled Mishimoto air filter, and the wire-reinforced lower induction hose will not collapse under suction and boost. Dyno testing showed maximum gains of up to 33 whp and 30 wtq (peak gains of up to 28 whp and 21 wtq) while maintaining safe AFRs on the stock tune — up to 70 whp and 70 wtq with a tune and intake using 93 octane fuel. This complete bolt-on installs in about one hour with common hand tools.

• Part number: MMAI-WRX-15BP (polished finish with airbox)
• Direct fit for the 2015-2021 Subaru WRX (FA20DIT, VA chassis; non-STI)
• High-flow oiled air filter (Mishimoto filter part number MMAF-3006) — increased filtration surface area; cleanable and reusable
• Enclosed airbox with protective edging; functions with the stock intake duct for cold air supply
• 3-inch MAF and lower pipes; wire-reinforced silicone hose prevents collapse
• CARB exempt — CARB EO sticker included; backed by the Mishimoto Lifetime Warranty
• Tune recommended where only 91 octane fuel is available — using this intake on 91 octane without a tune may damage the engine
