Not quite the improvement I noted in my 2011 Carolla. However, the 2013 Chevy Equinox (4 cyl) is not known for it's acceleration. Gas mileage has improved for an average of 2 MPG

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.

Haven't driven much yet but I had your filter before and worked great.

There was a noticeable difference in performance after installing this air filter. As advertised, acceleration was improved as was fuel economy.

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 have the 2013 Equinox 2.4L, I feel more power and seems to be doing better on MPG.
