Pleats of Strength: Deep pleats in the double-layered cotton create a 10-20% increase in filtration surface. This increase allows a greater volume of air to move more freely into your engine cylinders.

Fits like a glove: Green's hand-molded flexible rubber base offers an airtight seal and absorbs vibration. The 2-stage trimmable tabs allow for a custom fit and airtight seal, even in filter boxes that have been damaged or have slight surface distortions. The tabs expand and contract to fit in-between filter box sizes.

Precision production: Other filters use a simple pressure-molded injection process to bond the perimeter rubber to the interior components. That method saves manufacturing time, but in the process, a considerable amount of rubber can seep onto the filtering surface. While it may not look like much, that spill-over rubber can restrict as much as 25% of the intended air flow. Green, on the other hand, takes the time to ensure quality by using a 4-step production process which maintains maximum air flow.

Better Fuel Mileage: Increased air flow to your cylinders results in a more potent air/fuel mixture. In addition to the performance enhancements Green Air Filters offer, you'll also reap the benefits of increased fuel mileage.

PEAK TEST AT 550RPMS Increased Horsepower: Dynamometer bench testing on an 1800cc 4-cyclinder engine showed that a Green High Performance Air Filter provided a 6.7% increase in horsepower over the same vehicle with a stock paper air filter. Greater Air Flow: In a side-by-side test bench comparison, Green High Performance Air Filters allowed greater air flow through its filtering surface than paper.
