K&N filter debate

For over ten years now the auto engines are computer controlled. The computer determines the air to fuel ratio.Installing a filter with better flow, such as the K&N could potentially increase the air available to the engine.The computer sets the fuel air usage, so just because more air is made available to the engine, why would this increase HP or MPG?It's as though the makers of these type of filters think the OEM design is flawed. I think it's ludicrous to believe the OEM designers would fail to correctly size the air intake system.And yes I've heard of the display at the parts house showing air flow superiorty of the K&N over paper, making it look as though the paper is "choking" the auto. However they are using air flow (cfm) way in excess of what the engine requires. Dial down the air flow to realtime engine demand and I'd bet the paper filter does just fine.Rick

The NASCAR filters are gauze type material , like the K&N. They aren't oiled though. They are not listed as street filters but I would trust them over a K&N for filtering ability.

Definitely not K&N. Not even close.

True, not a K&N but it IS a gauze design LIKE the K&N. I have installed many of them in race cars.
