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.
