K&N Performance Cold Air Intake System: Easy Installation, Engineered to Maximize Airflow, Boost Horsepower & Torque, 77-2581KP

I immediately noticed a more meaty sound to the engine as well as an increase in power. I'm retired and have had my F150 for 20 months and only have 13,000 miles on it so I don't drive a lot. I've only had the intake on a couple of weeks and love it. I reset my gas mileage upon installation and actually at this point have lost 1 mile per gallon. Anticipated gaining gas mileage. Perhaps that will happen in time since all my driving has been in town! Time will tell, I hope.

I installed the K&N Cold Air System on my 2013 F150 FX2 with a 5.0 engine and six speed automatic transmission. Took all of twenty minutes to install. I don't have a dyno but the truck seems to be more responsive and my fuel mileage has picked a little. I would highly recommend this product.

Easy to install after you get the tight rubber hoses on... All that means is that they wont come off!!! Great sound and performance is felt right away. Unfortunately no gas savings yet (my own fault) because I can't seem to stop hitting the peddle to the metal... Great kit and great overall piece.

I noticed the difference in power and fuel mileage instantly. It only took about 10 minutes to install. I love the sound it produces with throttle response. I've been using K&N since the 80's on our offroad trucks, and now I use them on all my vehicles.

What a great product! Easy to install and noticed immediate improved throttle response and deep throaty sound in my 2014 F150 5.0 Coyote! Haven't noticed much gas savings but performance was improved and that's what I was looking for.

Wow. Easy to install and what a great sound when I put my foot in it. Still checking fuel consumption, but it seems to be improved.

Great product, just getting it broke in. I can already feel the throttle response and low end torque. Interested to see how the MPG will increase, if by just a little as gas prices continue to rise.

I love the throaty tone when I get on the throttle. Seems to be noticeably quicker. The nicest thing is at cruising speed it's as quiet as stock.

It's very easy to change. Very hard to tell the difference except for sound.

No performances noticed other than sound. It sound really good from outside the truck but on the inside it is horrific. It causes a major fibration through the pedals to the dash causing aloud rattle.
