i am considering either the af1 3'' on my 06 scab fx4 or the roush intake. i have ordered the offroad exhaust system. i haven't been able to find anything regarding the roush intake anywhere. does it require tunes and does it lean out the engine. thanks

 

i believe roush -aka airraid is the other one that waon't lean it out- save your money if you decide the roush ,get the airraid -they make it for roush-best to contact mike troyer and ask him www.troyerperformance.com

 

jcfx4king...did you just order the exhaust or do you already have it on?

 

i ordered it, i'm not sure if it has been installed yet, i'm in iraq. when i get home it is goin on if not already.

 

I would go with the AF1 intake from Troyer. I have the roush version & I love the look & sound of it until it starts droning( around the 1600-2000 rpm range ) From reading the forums the AF1 does not drone & it gives you the most amount of power gains. If you decide to get the roush intake then here's a link below to get it at the cheapest place I could find online.
