i see the stillen intake has a bigger velocity stack than the 06 rev-up but i like the oem air box setup better than stillen. Is there a way to incorporate the stillen stack with oem air box?

 

You could use the Stillen Z-Tube with the balance of the '06 intake they're all 3" in diameter, that's easy. If you like your intake air box just do it that way, nothing gained but a better sounding motor. A K&N drop in filter will increase the volume of air and it only needs to be cleaned every 2nd oil change. K&N filter cleaning kits available everywhere for $10=....does this help?

Really more after performance rather than a better a sounding motor (not a bad thing though) Is there a difference between oem z tube vs stillen?
Oh and thx for a reply

 

I dont think there is too big a difference. I have the stillen tube and am happy with it. I really doubt there would be any noticeable power between them.

Go for what you can get easier/cheaper imo
