    It is very easy to assemble and put on vehicle made with quality, sounds Great and looks awesome

    American Trucks had the easy viewing video for diy install. Install was simple and quick. So far a great product. Sounds great and can feel more horsepower/torque.

    I’m getting these emails quite frequently so here’s the review. 1K miles driven on E-85 5.0 SCSB Hwy miles are at 21 m.p.g. City miles Who cares? Butt Dyno is Muy Bueno Should have came with s pre filter or the reference to one that fits? I love the way is sounds, I run it in Sport mode 85% of the time. Would have been a 5 star but pieces were missing and dealing with K&N was less than fruitful so I adapted, overcame and improvised. Semper Fi

    Just had this installed and really pleased! Noticeable improvement in throttle response and the sound is awesome!

    Very easy to install – adds a nice grumble on acceleration. I can tell there’s more grab on acceleration as well. Just a bit more punch/HP. All in all I’m glad I did this install and now it’s on to an exhaust system.

    This thing is amazing, unbelievable sound difference. Honestly, took longer to put the parts together than to install. I would highly recommend getting this for your F150 if you have a V8. Also can feel the gain in horsepower. Only took about 10 mins to install but about 20 to assemble but definitely super easy.

    Easy installation, fits perfectly with the air box. Sounds great and you can feel a difference when you drive

    This thing definitely adds some noise when you get on it. I did not buy this from American trucks, but a honest review is what it is. I installed this on a 2023 F150, 5.0L, 6 inch BDS lift. This thing definitely sucks some air! The only downfall of this particular design is how it installs to the factory air box. Not even an oil change before I swapped back to stock. Keeping the factory air box bottom, and having the seal to the hood causes mad restriction. My filter started to collapse on itself. For the price I wish I would have went with a cold air with the entire air box, Roush for example. Works ish, sounds great and could definitely tell a difference while driving. 4 stars because I’ll have to modify it so it gets proper airflow. Looks good installed as well!
