K&N-Good or Bad

K&N filters increase air flow by NOT FILTERING THE AIR. Here's a simple test. Take a panel type K&N filter and hold it up to some light. You'll be able to see HOLES in the media. The cotton gauze element has voids in it. Many appear large enough for a grain of sand to pass right through.
K&Ns are good for racing or limited duty use where max performance is needed. They aren't that great for everyday daily driver use because they let more junk through than a paper filter does. I'd rather give up a few horsepower to keep the engine in my daily driver alive longer. Just my opinion.

If you are like some mindless robots on here soon you will think K&N is bad. It is amazing how many people on here do not think for themselves but that is the way of the world these days.

How much smaller is light than dirt? I can see light with a paper filter also, I know you can't see that though with where your head is.

He didn't say you can see light through a K&N filter. He said you can see HOLES in it. We all know you can see "light" through most any filtering media. But if you hold a K&N filter up to your eyes, you can look right through it.
This is nothing new. This is how oiled cotton gauze filters work. They require a film of oil to filter properly, because the cotton gauze is not nearly fine enough to filter on its own.

I put a drop-in K&N in my 92 VX and I don't worry about dirt getting in. I clean it every 15k to be safe.
IMO, with the way the intake turns and twists, it will take some miracle for any measurable particles of sand/dirt to even get to the filter...but I don't know for sure without a UOA. I'm sure some amount of dust is getting by compared to a traditional air filter, though. Dangerous amounts, though?

I wouldn't worry about it in Atlanta.
haha, good point. That was kinda my thinking as well.

I still have the one that came in the G5 in the basement and have been thinking about giving it a shot. If cleaning my MAF helps and makes some improvement in mileage, it may be a good thing to do with the filter service anyway, or shortly after to mitigate any oil concerns.
I see on their site they have a grease to seal the filter to the air box, anyone using that?

a lot of different greases are available to do that. Many people mess up when they install the air filter regardless of brand.
MAF cleaning is a necessary maintenance practice for us and none of our many vehicles have a K&N.

It's nothing you need to do often. Typically it would occur close to 75 or 100k miles.
I have had some dramatic improvements in the voltage signal leading to greatly increased driveability. Just be cautious!

Regardless of what AF I am running I usually clean MAF sensors when I change the oil.
