Description

This Performance Air Intake System allows your engine to breath more air compared to the restrictive factory air intake housing. It is designed, tuned, and dyno-tested to produce more horsepower and torque. The cone-shaped AEM Dry flow air filter is made from an oil-free, synthetic filter media that can be used for up to 100, 000 miles before cleaning is needed (depending on driving conditions). A custom shaped heat shield with edge trim lining is included to keep engine bay heat from the air intake. The air intake tube is constructed from mandrel-bent aluminum featuring a durable gunmetal gray powder coated finish. This air intake system is backed by AEM's Lifetime Limited . Some AEM air intakes are not legal for sale or use in California and other states adopting California emission standards, while others are 50 state legal.

  • 2019 Forester Sport sure feels more sporty.
Super easy install, perfect fit on my 2019 Forester Sport. Filter is up in the engine bay enough that water shouldn't be an issue but I still put a filter wrap on mine. Could not believe the coolant jug sized silencer hooked to OEM airbox. Loud when you send it, quiet during daily drive. Noticable difference in throttle response. Not sure I gained the 8 hp claimed by AEM, but it sure feels and sounds more fun. Also came with a license plate frame which adds 10 hp when installed properly. UPDATE: had it on and running for a while now. No issues at all, put stock box back on for a little bit and found myself feeling a dip in power ( I know, I was shocked) I put it back on and everything is right again. I know it's not making it a race car, but I'm trying to pull any power out of this that I can, no matter how small. ... show more

  • Well built, fits perfect!
I got this for the wife's MY20 Fozzy Sport. She's not a car enthusiast but has picked up some knowledge from my car hobby. She was actually excited to get it. AEM has been around for a very long time, and this intake is built to their high standards. Everything fit perfectly, included instructions were not the most detailed but the install was easy with the tools indicated in the instructions. As far was what the intake does, it adds a lot air induction noise and at full throttle, it's fairly loud. It's up to you to decide if it's worth the $. ... show more

  • Very sweet sound!
Just installed it on My 2022 Subaru Forester Wilderness! Fits great. Everything works. Also installed a Addw1 oil catch can. This is a perfect combo! The sound in SI drive is sublime . Worth the money!

  • Mass Air Flow Sensor issue
Was excited to get this and start installing it but the stock Subaru mass air flow sensor does not match the AEM holes as seen in images. So had to return it.

  • Look at the previous years of production.
Didn't fit. Wasn't returnable. Wouldn't purchase the product again. Did allot of research and was quite disappointed.
