Engines burn air, as well as gasoline or diesel fuel. And they burn a lot of it, almost 15 pounds of air for every pound of gas or diesel. Fortunately, you don't need to carry all that air around, you just filter that free air all around. Your factory air intake breathes its air supply from inside the engine compartment, where the air is quite hot from the engine and radiator. The Green Filter Cold Air Intake feeds your engine cool air from outside the engine compartment, because cool air is denser than hot air – meaning more oxygen per unit volume of air for your engine to burn. The factory air intake is often very restrictive and only feeds your engine hot, thin underhood air.
It gets better: the Green Filter cotton element is less restrictive than the factory element, especially if the factory element is starting to plug up with dirt. Again, that means more air into your engine and more power and less fuel. And instead of replacing the factory paper air filter regularly at some expense, all you need to do is pull out the Green Filter element, spray it with cleaner, let it set for 15 minutes and rinse it clean with cool water. After it air-dries, spray it with the special oil and reinstall. Constructed with woven cotton sandwiched between steel screen, the Green Filter element will outlast your car.
Long before they started producing filters for street cars, Green Filters made custom air filters for the motorsports industry, with clients like MAZDASPEED, Chip Ganassi Racing, Saleen, and Toyota. These top names in road and off-road racing chose Green Filters for their superior performance and constantly-improving technology. Producing the same type of filter in fitments for street cars was a simple step, and the line of vehicles covered is constantly expanding. Better yet, their continuing role in motorsports keeps them at the cutting edge of air filter and cold air induction system technology.
