Only gains ive noticed are on the interstate going up long grades. Before the K&N filter, I'd constantly have to grab 4th to get up to speed (65-70) but now in 5th I have to let off the gas at 80mph or risk getting caught speeding. Not sure about fitment of the filter...the only way that it would work is to have the pleats facing the incoming air whereas the original had the flat surface towards the air and the pleats facing the throttle body. Didn't see any airflow direction marked on the filter so i ran how it fit and it seems to work ok. I like the sticker too wish i get a couple more somehow. Good product its sturdy you can feel the quality its not like the flimsy lighter than air filters you get from the parts house.

Everything was fine. Would purchase again.

I put the filter in my Nissan and have immediately noticed an increase in horsepower. I am very, very pleased with my purchase and would highly recommend it all. I appreciate the hat you sent me also and will gladly wear it and display the K&N name. Thanks again for delivering on your promise.Greg Evans,GA
