Mishimoto Polished Cold Air Intake Kit w/ Box Subaru WRX 2015-2021

Part: # MMAI - WRX - 15BP. Mishimoto has crafted a top - notch performance air intake tailored specifically for the 2015+ Subaru WRX. This intake comes with several cool features. Its wire - reinforced lower induction hose won't collapse under suction and boost, ensuring reliable performance. Dyno tests show it can deliver maximum gains of up to 33 whp and 30 wtq, and peak gains of up to 28 whp and 21 wtq while keeping safe AFRs on the stock tune. With the Mishimoto tune kit and 93 octane fuel, you can even get up to 70 whp while maintaining safe AFRs (check the dyno chart in additional images). It has a really aggressive and unique tone when you accelerate and boost, and its free - flowing design makes the turbocharger spool and BPV sounds louder. Watch the sound video to hear it. The stock intake duct is used to send cool air to the high - flow Mishimoto oiled air filter. This filter has more filtration surface area than the stock paper filter, and it can be cleaned and reused for a lifetime. You can choose to have an enclosed airbox with it. This not only protects against engine bay heat - soak but also gives your engine bay a stock - like look. It's a complete bolt - on part that works great with the stock tune and can be installed in just one hour using common hand tools. Made in the USA, it's available in either polished or wrinkle black aluminum intake piping and comes with the Mishimoto Lifetime Warranty for top - notch quality and craftsmanship.

Using this Mishimoto air intake kit is a breeze. First, make sure your car is turned off and cooled down. You can install it using common hand tools in about an hour. Just follow the included instructions to bolt it on. When it comes to the optional airbox, you can choose to install it based on your preference for heat protection and engine bay appearance.

You should clean it periodically, depending on how much you drive and the conditions.
