Okay, so I had a K&N panel filter, but it was filthy, bugs and grease/oil in it. So, today I cleaned it with dish soap. I also noticed the oil breather going through the air box. Now that can't be good there. Especially with it being all oily. So, I yanked that out, cut out the little piece for the hole from the filter so I wouldn't have a hole for a mouse or something to get into and chew up the filter. Then, I went to O'Reilly and bought a 3" K&N breather filter, cut the hole out bigger so it fit on the plastic pipe that came out of the old tube that ran to the air box, and I also bought the K&N recharger kit and cleaned the old filter with that, which made it look almost new. I also cut a hole in the front of the intake tube that goes up and mounts to the radiator support piece. I figure since the regular hole at the front of the intake is smaller, I'd cut a hole in it lower for some more air. It's closer to the grill, so it gets more air and colder air. It may get more bugs, but I'll be cleaning the filter more now that I have the recharger kit.
I definitely notice a difference. It doesn't run as loud as it used to. It sounded like it was running hard before, now it seems to just run smoothly. I'm sure this should add to my gas mileage, even if just one or two miles per gallon. When I cleaned it, I found at least one bug inbetween each ridge, though it was probably more like five. Now there's more room in the air box and it doesn't have oil fumes. If someone would like some more pictures, I can take some and have them up by the end of next week.
