K&N Intake...any good?

I know they're good with the gassers, but my brother said he thought he heard something about them being no good on the diesels. I have one that came with my 2000 when I bought it, so is this thing worth cleaning or should I spend my money on a better intake?

Thanks,
Matt

Somebody posted a review/test that showed the K&N as being dead worst for letting dust into your engine. They flow air well, but also flow dirt well. If you do any off roading, or drive on dusty dirt roads, I would get something else.

Could be this. Some have reported the K&N not sealing very well in the PSD airbox, not sure about that one way or another, but most here will tell you, PSD=K&N = BAD.

throw that thing in the trash.... it does flow too much dirt particles that will mess up your turbo wheel... get a new intake like the best AFE stage 2 or air-aid intakes... if your short on money i would suggest to do the DIY tymar intake.. it would cost around 100 bucks or so to do it yourself.....

Thanks GCOP. Good article, but not the one I was thinking of . The one I saw gave similar results, but had charts and graphs. Not sure if that means it was a better test, but charts and graphs make it "look" like a more scientific test.

K&N = Bad period...diesel or gas. Production quality is WAY down from where it was 5-6 years ago. Your better off tossing in a regular old filter or doing the DIY Tymar or Ford Extreme Duty intake thingy. The quanty of air doesn't mean anything if it's full of dirt and poo. Quality of air is more important.

My dad has the K&N intake system, the whole intake tube and big cone filter and all, it is not bad. Frees up air flow a little. But you have a 6.0 so your stock intake is pretty good, I would not change that until you reach like 400+rwhp or so. If I were you, I would go for an exhaust or something like that, the 7.3 guys need to upgrade their intake more than 6.0.

From what I have read its the drop in k&n that is like the stock filter that sucks, but the K&N's that are like the AFE intakes are okay. The drop in lets too much dirt past the filter.
