Which one is the best? What do you all reccomend?

 

I have one, but I would suggest putting the money towards a tuner like the Edge Evolution. Not sure the cold air intake makes a noticable difference, yet the Edge adds a definate improvement.

 

x2 on Tuner first

but I really loved my Volant. made my truck sound like a big ol' 460 with a Quadrajet was under the hood...pure muscle sound. I miss that noise alot

I would recommend you skip the Roush one...never did like that thing when it was installed. The Volant was better built and seemed better product overall. The Roush seemed like someone got told to build it, and only had 1-2 hours to get it done.

Did the volant do anything for mileage?

 

I did a Banks on my 5.4 08'. I got a couple more mpgs but you have to keep your foot off it. It definatly adds some tone in the shift zones though, as well as when youre ***** to the wall. I get 18 to 20 if im driving Ms. Daisy around town. 13 or so if im hammerin down. most ive gotten on the highway was 26 after a couple hundred mile trip.

 

don't know honestly

I installed the Volant at 500 miles. It was installed for 22,500 (ish) miles and then I switched to the Roush Supercharger.
