    13-17 Cummins 6.7 Custom RPI Diesel 5" Intake?

    Has anyone installed one of these things on their 6.7, seems more for show than performance due to all of the powder coating options.

    Can't help you with that but I was really close to ordering one a little while back. Have a local shop that fab'd up a 5" intake and swore it helped. They do look good tho just not to sure how much I want to go back to cleaning filters.

    I talked to them for quite a while when I got my traction bars. They flow far better than S&B

    Only reason I haven't got mine yet is I'm buying another house which is more important first

    You can get it basic without fancy colors

    Spend a little extra on the higher end filters he offers for it

    Would an aluminum tube help the turbo sing a little better than a plastic one?

    People that run them already do say they are getting more of the turbo spool sound they like hearing. Sinister makes one similar. I don't remember how much theirs costs but may be slightly cheaper since. Will only be the blue that Sinister offers parts in

    It looks like an awesome CAI with the 5” pipe and you add whatever air filter you prefer to run
