Mishimoto has crafted a top - notch performance air intake tailor - made for the 2015 - 2021 Subaru WRX. This intake comes with a host of innovative features. The wire - reinforced lower induction hose won't collapse under suction and boost, ensuring stable 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 see gains of up to 70 whp while maintaining safe AFRs (check the dyno chart in additional images). It has a unique, aggressive sound under acceleration and boost, amplifying turbocharger spool and BPV sounds. Check the sound video to experience it. The stock intake duct supplies cool air to the high - flow Mishimoto oiled air filter. This filter has more filtration surface area than the stock paper filter and can be cleaned and reused for a lifetime. You can choose to add an enclosed airbox to protect against engine bay heat - soak and keep a stock - like engine bay look. It's a complete bolt - on 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 polished or wrinkle black aluminum intake piping and comes with the Mishimoto Lifetime Warranty, guaranteeing excellent quality and craftsmanship. Key features include direct fit for 2015+ Subaru WRX, dyno - proven power gains, aggressive intake tone, optional airbox, high - flow filter, non - collapsing hose, easy installation, USA - made, multiple pipe finishes, and a lifetime warranty.










Using this Mishimoto air intake kit is easy. First, gather common hand tools. Then, install the kit following the provided instructions. It should take about an hour. The kit works well with the stock tune, so you don't need to make any major adjustments. For the high - flow oiled air filter, clean it regularly to maintain its performance. You can use a filter cleaning kit designed for oiled filters. When it comes to the optional airbox, install it if you want to protect the intake from engine bay heat. Keep an eye on the wire - reinforced silicone hose to make sure it doesn't get damaged. If you use the Mishimoto tune kit and 93 octane fuel, you'll get even better power gains, but always monitor the AFRs to ensure safe operation. With the Mishimoto Lifetime Warranty, you can be confident in the product's quality, but if you have any issues, reach out to their customer service.
