Filter for 2010 Miata and 2015 Civic. I haven't had but one drive with the Miata, and I think there is a difference, but with the Civic with a five speed, I'm getting 40 miles per gallon on the highway, and almost that on secondary country roads. I'm still breaking the car in gradually, so I haven't had a chance to really test the performance, but so far, VERY positive results!!

I always replace my stock filters with K&N filters for fuel mileage and to protect my engine. Now I need one for a 2013 Honda Civic with the 1.8 liter engine.
