A Fram air filter will ensure optimum engine combustion by creating the ideal balance in air/fuel mixture. Fram Air filters improve the air flow in the engine and allow for better engine performance and superior fuel economy. Fram air filters contain fine media paper to ensure that all sizes of dirt is collected and removed from the air entering the engine. Correct fineness and pleat geometry provides filter stability. Fram panel air filters have the right density PU to ensure a tight fit in the air filter housing. Therefore no air by-pass is allowed, ensuring the engine is protected from the airborne dirt. Dont starve your engine of air! Improved air flow to the engine equals better engine performance and superior fuel economy.
