Air Filters For Your Trucks
So what air filters do you run in your gas/Diesels besides K&N? Time to replace mine and looking toward Fleetgaurd but could o with the OE Mopar.

K&N is a bad choice be it gaz or deezal! As noted, it not bad at filtering. It's the oils that get on the sensors after it. Like you MAF, manifold pressure sensor etc. That's the issues you will have. Especially if you over oil the filter.
Better to use best quality paper AF you can get ahold of.

True story, my MAF got oil on it and sent a code on my LB7 years ago.
Most codes were not due to oil on the sensor. It was from the sensor being out of range. Most sensors back in those days were narrow band sensors meaning they only read a narrow range and anything out of that range(like more air) threw a code because it would mean that the truck had to guess on how much fuel to add. You do not have the same issue with todays wide band sensors that have much larger ranges.
If auto manufacturers were so worried about oil in MAF or MAP sensors, then they would not sometimes put them after the oil dump for the positive crank case ventilation or the EGR valve which introduces spend exhaust gas. I can guarantee that these two things would put these sensors through more oil and contamination than an oil bathed filter would.
This was my MAP sensor on my BMW diesel car. It was located in the intake after the EGR and oil dump, and all that black oily soot on my fingers came from the sensor. Nothing wrong with it. I just cleaned it and put it back.
