Like Chris said, yes it will increase your mpg. But not so much that you will notice everytime you fill up. In the long run it will save you alot of gas. You might see 1-2 mpg difference at each fill up, but that adds up over time.

Also doing a good quality tuneup, keeping your tires inflated to the proper pressure and using good gas will all help increase your mpg.

All of these added together will make a dramatic difference if you are getting poor mpg. Keeping your engine healthy is the biggest key to getting good mileage.

I stand behind K&N filters also if for nothing else than it is cheaper in the long run then replacing your air filter at the recommended intervals.
