Had it in my 2013 Honda Accord for about 1500 miles and have gotten high 20's to low 30's combined [mpg] around town and freeway. Prior to this got anywhere from 24 to 29 so I like it right now and will continue seeing if the inproved gas milage stays. By the way the increase milage is approx. 2 to 3 mpg.

Great product! I'm already seeing the increase in power and gas mileage.

I have always had a K&N filter or intake system in every vehicle I own. So when when my wife got a new Honda Accord I ordered one right away. No surprise, great product! The fact I got a free hat was just a bonus!
