    Every thing about this product is great exactly like the promo said it only took 30 minutes to install that's from the time I raised the hood to when I started the engine removing the factory intake and installing the F&N totally easy. Way faster response more power and the fuel is 10% better not to mention I love the sound when taking off and on passing

    Awesome Addition

    Took me about 45 mins to install. The intake has added more power right out of the box. The sound is awesome when paired with or without duals. The biggest change is in the upper gears especially if you are climbing a hill. I would recommend to anyone who whats a deeper sound. Gas Mileage seems to be a little better, but too early to tell.

    What a waste of money

    I thought this thing might help my gas mileage. Nope, and it makes a stupid sound when accelerating, almost embarrassing.

    Fast shipping, with great savings at this time of year. Took about 1/2 hour to install and boy does it sound great when you get on it.

    I installed this at the same time as aneeded Airaid throttle body spacer. It was very easy to install and sounds great! The increase in HP is amazing!

    Great upgrade in sound and performance in my 2014 F150 supercrew

    Installation was fairly easy and there are YouTube videos that walk you thru it as well. One completed on my 2014 Ford F150 platinum supcrew, I was amazed at the sound improvement. There's a huge increase in the aggressive tone of the 5.0 litter V8 when push the gas pedal down. I'm very happy and satisfied.

    Nice Product
