Car owners throw away the highly efficient pleated paper filter which is sized for twice the air flow requirement of the engine to allow for particle loading and replace it with a K&N low efficiency filter. Stupid is as stupid does!

The only benefit of a K&N is at the maximum rpm of an engine when the pumping loss of the engine is lowered. If anyone thinks this filter will benefit a Model A is sadly mistaken. A K&N filter application on a Model A tells me the owner knows nothing about engines.

Take a K&N filter without the screen, hold it up at eye level, peer through the filter, and watch white cars go by! If you don't believe me, compare the filtration efficiencies!

My Model A has an Air Maze with pleated paper. This filter offers protection against lubricating oil particulate which is extremely important because the standard Model A has no full flow or by pass filtration system for the lube oil.
