Description
The Mishimoto MMAI-WRX-15BWBK is a Wrinkle Black performance air intake with enclosed airbox built specifically for the 2015+ Subaru WRX. At the heart of this kit is a wire-reinforced lower induction hose engineered to resist collapse under suction and boost, paired with a high-flow oiled air filter that offers more filtration surface area than the factory paper element. On the dyno, this cold air intake produced maximum gains of up to 33 whp and 30 wtq, with peak gains of up to 28 whp and 21 wtq, all while maintaining safe air-fuel ratios on the stock tune.
Beyond raw numbers, this air intake system is designed to be a true bolt-on upgrade for owners searching for a reliable cold air intake alternative to other cold air intakes, k&n cold air intake, s&b cold air intake, or afe cold air intake options on the market. The stock intake duct is retained to continue feeding cool, dense air into the Mishimoto intake filter, while the free-flowing design amplifies turbocharger spool and blow-off valve sounds and produces an aggressive intake tone under acceleration and boost. The included enclosed airbox helps shield the intake filter from engine bay heat-soak while preserving a stock-like appearance under the hood. Because it’s an oiled, reusable intake filter, routine cleaning and re-oiling can extend its service life instead of replacing a disposable air intake filter.
