I have always used, and believe in, only genuine OEM filters for my cars.

YMMV of course. Just my 0.02.
Our car doesn't have a MAF. My 350Z did. I ran a K&N filter for 5 years. One time, I oiled the filter so much that my car left a puddle on the ground, I thought it was leaking oil! My MAF was not affected and my 350Z made great power.
