Fits perfect in my 2018 Subaru WRX STI non Type RA. Dropped in within a minute and can tell the seal perfectly made all around and better throttle response. Will see how this filter last and update.

No more oily mess. These are dry filters, which means they are easy to clean and don't need to be re-oiled like the old style. Will this increase horsepower? No not directly, but compared to the oem paper filters which clog within a few thousand miles, this will not only outlast stock but won't restrict power for thousands more miles!
AEM® DRYFLOW® drop-in replacement air filters are oil-free, easy to install into your factory air box, and simple to wash and reuse. Designed with precision, our cutting-edge filtration technology utilizes a thick 3D filtration media to help increase airflow, and offers top-quality engine protection. Go up to 50,000 miles before cleaning (under normal highway driving conditions), and feel confident purchasing under the Lifetime Limited Warranty.
