K&N air filter suppose to be bad for these trucks??? Are you sure?

After running my K&N air filter for about 20K miles and after about 2K miles from last oil changed I decided to see what the oil report had to say.

Well looks like my silicon is not bad and they do say the air filter does seem to be working.
SO?

"THEY" say Obama care with work too! I have been running K&N's on different vehicles for many years, 60k on my K&N in my 7.3. "THEY" say they K&N will destroy your turbo...mine looks like new.

K&N is a reputable company who does a lot of research on their products.

I have K&N also, am changing FICM so it was easier to remove intake from turbo.
Turbo looks fine. I think it was bad installs, not getting it sealed right at the connectors.

My next oil run/test will be 7,500 miles as I don't think an extra 2,500 with EGR blocked/disabled and DPF removed will hurt that much.

If there's no problems after 7,500 miles then I say for me MYTH busted for these rumors K&N air filters will DESTROY a 6.4L.

I think people who have had problems had air leaks and of course if they were running oil reports they would of caught whatever the problem was even if it was a K&N air filter or not.

I do drive dirt roads but at low speed due to hauling Polo ponies and my dually is not an off-road race machine but a Cowboy Cadillac.

My truck spends 50% of its time off road. Sandy and dusty conditions. I think it boils down to poor install or upkeep, or blaming the K&N for a failure just to have some where to point the finger.

I love my K&N and have had excellent results from everyone I have run.

I don't run K&N due to the tests done with K&N filters when I was big into fourwheelers. Some guys actually did several tests with a substance similar to dust and dirt and used a black light and you could see a severe amount that had pasted through and into the intake track and carbs.

I have a turbo wheel out of my 7.3 that would dispute your claims. Maintained regularly. Wheel looks like crap. 100k on it maybe?? before I heard about it and checked it. Run it if you like don't make me no nevermind.
