RoushCold Air Intake Kit 2.7L/3.5L Eco Boost F-150 2018-2019/F-150 Raptor 2017-2019

After installation, the intake noise can be heard in the cab. It is not real loud. Gives it a little bit more of a V8 sound. Still long ways to go to sound like the 5.0. It does have some HP gains, nothing wild. Haven't noticed mileage difference, yet. Most people don't buy these for gas mileage though I have not tuned mine yet, due to warranty. This is where the tune and CAI compliment each other. Installed with no issues. Not sure it is worth the money, unless your adding other mods. I would still buy it either way.

Looks awesome and added a bit of sound. Install was simple and fast. Fit the 21 Powerboost 3.5 perfectly. No noticeable MPG change but have little to compare it to.

Incredibly easy to Install and great price. Only had two issues, the IAT sensor broke when removing from the old air box. And one of the bolts that hold the filter in the box was not threaded properly.Nice low tone from the intake when you hop on it, and the turbos are a bit louder. Love it!

Just as advertised. Great product and looks great. Only thing to be aware of is that you make sure that you print the template for drilling at %100 or the template will be off. Most printers are set up to Fit to Page and it will be a little small if you print like that.

My package had the wrong part for EPDM Coupler - Air Box to Tube, 1115TT-9B661, which has a different diameter on each end. The part that I received had the same diameter on both ends. Since I had it all torn apart and tools and supplies out I decided to squeeze it down to the tube diameter instead of sending it back and hope that didn't effect performance or longevity.Also I was disappointed, the dirty air intake was a snap-in fit on the factory airbox, on the Roush airbox it was a sloppy fit with up to 1/16 of an inch gap which will allow air, dirt, and water in. I'll probably put some sealant around it to help keep those out.

*2019 F150 Limited 3.5 H.OEasy to install, fast shipping. Not sure if I feel any difference but I think it looks great compared to factory setup.

Driving the same distance ( 53 miles). Same speed(70mph). I saw a increase from 14.2 mpg to 15.6 mpg so far. Noticeable Increased to Throttle response and feels like increased power in the higher r.p.m ranges.

Cant say it was worth the money but it was an easy install. I really dont see any improvement in my 2021 3.5 EcoBoost. Not in sound, or performance. This is a mod that you will see benefits from if you go all out and end up tuning, and swapping other parts like the intercooler, turbos, exhaust etc. If not you're just paying to say you have it.
