Advanced Flow Engineering (aFe) has developed a new high flow air filter for the GM Chevrolet gas and diesel pickups. The mounting plate and heat shield is secured to the three mounting bolts that held the stock air box and filter. The new filter flows the most air of any currently on the market.

While flat filters by themselves flow enough air, the factory air box restricts airflow. aFe’s new large cone air filter should flow enough air even for modified engines. aFe's Magnum Sport lifetime filter has a radius entry in it's large 4.5" opening for extreme flow, as well as a filtered opening at the far end. Filter Minder is transferred to unit.

Kit includes, heat shield/mount, filter and molding/seal. You utilize existing clamps, hose, filter minder and grommets.

aFe Filter Cleaning Instruction


Preparing --- Gently tap the filter to remove excess embedded dirt. Gently brush the remaining excess dirt from the element with a soft brush


Soaking --- Using aFe restore cleaner, spray the element thoroughly soaking the cotton media. Let it soak for approximately 10 minutes. For large elements, or where a quantity of filters are to be cleaned, put an inch or more of cleaner in a pan and roll the filter in the pan thoroughly soaking the element. Again let it soak for approximately 10 minutes.


Rinsing off --- Using low pressure from a tap or a hose, run water from the clean side to the dirty side until the water running through the element comes through clear. DO NOT USE HIGH PRESSURE or a nozzle that sprays a sharp stream.


Drying --- It is best to let the filter dry naturally. It is OK to lay the filter in front of a fan to speed drying. Do not use heat or high pressure air as it can cause media damage.


Oiling --- Using aFe special formula aerosol air filter oil, spray a wide band of oil. Let it set 20 minutes and it will wick throughout the element. If light spots appear spot touch those areas.


Note --- Sunlight deteriorates the oil. If the filter is exposed to sunlight for extended periods of time it will be necessary to re-oil the filter.
