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 purchased this K&N Filter for better performance and increased MPG. It arrived in a timely manner and at a reasonable price. This is my second purchase of this type of filter for vehicles I own. The filter is an exact fit and easy to replace with less maintenance over the years.

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