I use an intake air filter and oil filter on my 1995 Honda Civic.  I have noticed about an 8% improvement on gas mileage with these products.

Bought this air filter at the store yesterday and put it in. I can definitely tell a difference, not an amazing cold air intake difference but there is definitely a noticeable difference. I test drove around quite a bit and really liked the difference. 5 stars, and by the way I put this into a 2004 Honda Civic EX 1.7l

Quality intake, very easy install you can do to upgrade your car. I installed it in my 2015 Honda Civic SI sounds like a beast now, and you can feel the difference in acceleration. Would recommend to anyone thinking of installing one. Would recommend the installation video rather than the one that comes with the kit. No regrets with my purchase :)
