Universal Oiled Short Cone Filter by PRL Motorsports

Our oiled filters are constructed from high quality, double layer cotton to increase the filtration surface by 10% - 15%. This causes air to move freely while maintaining superior filtration, trapping particles as small as 5 microns! The cotton filter is encased by coated steel mesh to ensure your PRL Motorsports air filter withstands the toughest of conditions!

Each filter is hand-molded using a flexible rubber base to ensure an airtight seal and absorb vibration. These filters do not use pressure-molding like other manufacturers, which can cause the rubber to seep into the filter element blocking airflow by up to 25%! Our air filters utilize a precision four-step process to virtually eliminate rubber seepage and maximize airflow!

Always good

There is always good count with PRL products. PRL=QUALITY.

Great Replacement

Decided to replace the cone off the PRL Cobrai CAI instead of cleaning it! Left one has 12,000 miles on it, right is the new one! Great quality product from PRL. As always, MAP has the cheapest prices and fastest shipping!
