I used to do a k&n every 40k or so maybe about 3 years but this thing has been super low maintenance and I got 7 years out of it before tripping the MAF up. I live in northern Virginia with the full four seasons driven down to Alabama for a summer and a trip to Michigan during the tail end of winter. Lowered on knobs 4wd Tahoe e85 only currently have 285k oem engine and transmission.
I had great service and I am pleased with the filter
Everything was fast and easy. From purchasing to delivery.
First time using so not enough to time has passed to rate the filter. But great customer service and people, great overall experience.
Works great. So easy to install.
Got my Suburban back up running well.
