I've been using K&N for years now. I recommend it to all friends and family. My wife likes it in her 2014 Chevy Euinox car now she says she gets better gas mileage and gave her a little more power. I got one on my 2007 Chevy Silverado LT and on my 1971 Chevy RS Nova. I wouldn't buy anything else but K&N . I even use the K&N oil filter too.

I have a K&N filter on my Harley, one in my equinox and had one on my 500SL before I sold it. All were easy to install and felt subtle changes in idle, mpg and peppiness for all applications. The most recent purchase is for my 2010 equinox. My vehicle gets better highway mileage but overall combined is still near the same as before. The engine is less strained during acceleration and highway mileage is much better. I mostly do stop and start city driving so I am not seeing a significant combined change . However if I reset my average when I do highway I see I can get 2mpg better than before. Easiest upgrade you can do for your 3.0 V6. Takes about 15 minutes to change filters. Next is to install on my 2003 corvette(16000 mile beauty).

I've bought air filters for my last 3 trucks and seen no reason to stop. And also a air tube for my GMC. The vehicles run better with them.
