Air Filter question

[bamaboy473]

The 2000 Excursion I bought came with the OEM air filter box, but had a K&N filter in the box. I've cleaned and oiled it, but is this filter going to allow more air flow, or is it just a re-usable filter that's designed to save money?

It is a performance filter that flows more than stock, but on the down side it is less efficient at filtering dust.

Thanks, Pipe. I'd read about the DIY mod that Maintain posted (with good photos, too). Then, going back to that section, I found another article he wrote that covers the K&N filter and both you guys are on the same track about it not filtering dust real well. We don't have lots of dust down here, but salt air is an everyday thing, so doing the mod will make me feel better about what the engine is eating.

This is a picture of a K&N filter after a weekend at the Sand Dunes, those black circles on the filter are holes from the sand being sucked through the filter by the turbo. Luckily I had no major engine damage. I recommend you find a different air filter.

Yep get rid of that crappy K&N. I ran them on everything I own until I saw what was getting past the filter onmy diesel. The DIY is the ticket for the 7.3. It sounds awesome, saves money and let's that thing BREATHE.
