Excellent product! Took about 30 minutes to install, directions are simple and straightforward. After installation, my truck has a faster response when I hit the pedal, added a bit more horsepower, and definitely sounds more aggressive especially with my borla catback.

The biggest difference after installing the K&N 71 Blackhawk air intake was the throttle response. It was greatly improved. Given the increased acceleration, without access to a dyno, I would be inclined to believe that I had also increased the horsepower by 5%. Installation was a easy and instructions perfectly clear.

Super easy to install (be careful with the clips) that only took about 30 minutes. I love the sound this makes and am getting an mpg boost (depends on how you drive) on my daily commute. Well worth the money. Only downfall is the whistle noise I hear when maintaining speed or starting to accelerate which is common in aftermarket CAIs. However once you push down on the pedal, it goes away. Read lots of reviews and it's normal due to no baffling that the stock intake has. Overall, still worth it!

So easy to install, even for an auto novice such as myself. My wife is so impressed that she wants to trade her new carrot you F- t50

It was a very easy install. It also looks aggressive and nicer than my stock parts. I CAN actually tell an increase in horsepower. Not a huge increase. But something is better than nothing. Also when I accelerate quickly it sounds very aggressive. Definitely worth getting.

Materials and design are great but I think the filter, housing and intake tube could be a little bigger in size. My truck did not gained or at least I do not feel any performance difference vs stock. 2015 F150 5.0 V8
