Bought this after I realized the dealer lied about changing the air filter. My fuel mileage doubled and my pickup has much more pickup; had to throw sandbags in the back to maintain traction. I've always bought K&N because I love spinning tires, but if you like fuel mileage, these things help immensely.

Best air filter in the book. You can feel your engine sucking in better air as soon as you start your truck after installing it, and they last forever. Great product, this is third time I have put in my trucks. THANK YOU K&N filters!

Fuel economy up and horse power increased. Mpg increased by 6 miles. Definitely game changer for me. I would recommend a K&N filter to anyone looking for increased mileage and/or horse power. My vehicle is a 2014 Toyota Tacoma TRD.
