The spacer was simple to install. the instructions could provide a simple drawing for the very inexperienced. It does not whistle as I drive (I read this from another review). I have not noticed a significant amount of power. The on board computer averages fuel consumption while on the freeway cursing at 1999 RPM's in overdrive the average went from 17 MPG to 19 MPG, ( it could have been great tail wind). I have only had it installed a week now and have driven 300 miles.. So far it seems to be a good product. John

I installed this on a F-150 with the 5.0 and it did make a little difference on the low end. Gas mileage increased slightly maybe. The real big difference is the sound this motor made before when you stepped on the gas, you could really hear the air sucking in the intake. This little device made it quieter. Really easy to install. I had to do some clean up of plastic fibers that was hanging on the back side because it looked like they would drag air.
