Installed the K&N filter in just a couple of minutes. Fuel mileage was averaging 26.5 to 28.5 before install. After new K&N install it increased to averaging 28.8 to 30.1. City and highway driving combined.

Happy 03 Nissan Frontier owner.

Quick delivery and nice product. I think I am gaining at least an extra 15 miles per tank.

I purchased a K&N filter for my 2004 Nissan Frontier and am very confident I made the right choice! I have been using them in my vehicles and on my Harleys for a number of years now and they perform as promised! The best filter you can buy, period!!!

Good Purchase

Have been using K&N filters on every vehicle I own for over 25 years! It's the only way to go! Better mileage, more power, and washable.

Great Product!

Improved the sound a little. No noticeable gain in horsepower. A little better fuel consumption. Quality is excellent!

K&N air filters best choice

Probably the best choice to provide adequate protection without undue restriction. I have used K&N filters on several high performance vehicles with good results.

I can tell by the sound of the engine that it is getting better air flow. I drive eighty miles a day and I have been getting about two miles per gallon better gas mileage than before. Great air filter.
