FA20 engines love air, so why not give it to them? The Mishimoto 2014-2018 Forester XT intake will give your Subaru that extra amount of power that it needs. your Subaru's twin-scroll turbo will quickly draw massive amounts of air through the 3" mandrel-bent pipe and high-flow filter. A tune is required to run this intake because of the large-diameter piping, but the results are well worth it. The included black powder-coated airbox defends your air filter from the dreaded heat-soak by isolating it from the rest of the engine bay. This Forester XT intake changes the positioning of the MAF housing slightly, but don't worry, this kit includes a MAF extension harness to keep installation simple. With a Mishimoto Forester XT intake, you'll have no issues getting anywhere on time, and you'll sound good doing it.
