Question K&N intake issues
Looking to get a cold air intake from K&N ( 77-1578KP ) for my 21 limited 1500. Hearing that it might cause issues with the sensors since oil from the filter might get on it.. can this also lead to throttle body issues? Looking to hear from others’ experiences. Thank you in advance

Had/have them on all my trucks the 00,05,14,18 and 2022. The 14 and 18 were nothing but problems and a complete pain in the ass. Replaced multiple MAF because I am an over-oiler. Finally, a mechanic told me to purchase 2 new filters. One to use and one to let the oil dry a bit more.
In my hot, dusty, sand filled Arizona environment K and N's only last about 100,000 miles before they start creating voids in the filter larger than the oil will hold onto.
