Before purchasing this K&N Filter from Auto Anything, I had purchased others for my motorcycles. So I know K&N makes a great product and saw the dyno results on my high performance bikes already. What I didnt expect was the results when I put one in our minivan. It will be a long time before the van can pop a wheelie but right away I was getting 1 to 2 more miles per gallon of fuel economy. For us thats a big deal and adds up at the end of the month. Thanks Auto Anything!!
