13-18 Cummins 6.7 Custom RPI 4" Intake System
This is our full metal 4" Cold Air Intake system for 13-18 Cummins 6.7
The 4" Intake will run better and make more power than our 5" system would on a truck without the custom tuning to re-scale MAF.
The 4" does not need tuning to rescale MAF.
You will need to leave active air servo motor unplugged
This system uses a 4 Inch T6 Aluminum intake tube for ultimate air flow!
You will have faster spool up, lower egt's, Noticeable Horsepower gain, some Mpg gain, and a turbo whistle that will make people look when your going through town!
Our system adds 25+ Horsepower!
Has a bolt in heat shield that is very well sealed to keep underhood temps away from the Filter, it provides a fresh cold air supply straight to the filter for lower egt's and better performance. It is normal to see 150-250 deg drop in egt's with this system.
We use only the best filters on all our intake systems
These are Custom built to order, so it takes 10-14 days to ship out, depending on how many orders we have that week.
