Green Filter 2028 High Performance Air Filter Recharge Oil - 8 oz.

Green High Performance Air Filters come pretreated with a specially formulated dirt-trapping oil. Our proprietary lightweight synthetic Green Filter oil is designed to not damage any vehicle sensors. This oil creates a positive (+) magnetic charge or ionic bond with the filter's stainless steel mesh. The positive charge attracts the negatively (-) charged dust particles entering the filter causing them to cling to the steel mesh and allowing the cotton to remain clear for maximum air flow. Green Filter oil also contains a swelling additive for the cotton filtration media. This causes the cotton fibers to swell which allows the filtration media to collect the very small dirt particles (down to 5 microns) that could otherwise harm your engine.
