K&N Air Filter for 6.4L Ford Powerstroke

[Bob&Patty]

Tom, the $64,000.00 question is........if the OEM filters DO NOT have oil in them and the K&N does. Well how in the heck did the oil and dirt get into the MAF????????? BTW, I watched the video what a lying sack of bull durum that guy is. I think I saw him in a Abbott and Costello movie.

It's a little older now, but the link shows a pretty extensive test of airfilters, after this came out I pulled the K&N off my truck.

Now I am beginning to understand why my mass air filter on my 99 F350 7.3 went out and also why the engine blew at 150000 miles. I should have never put the K&N air cleaner on it. Hindsight is always 20-20.
