07-12 Cummins 6.7 Custom RPI 5" Intake System

Regular price $354.99

This is our 5" Cold Air Intake system for 07.5-12 Cummins 6.7 this is the biggest system on the market! 

***This system should have custom tuning for MAF sensor calibration. Meaning with efi live or mm3 tuning you will need to have your tuner re-scale the MAF sensor for the 5" tube so that the truck fuels the way it should with the bigger intake.*** If you do not have Custom tuning to be able to re-scale the MAF sensor, than our 4" version will be what you need, in fact the 4" will run better and make more power than the 5" would on a truck without the custom tuning.

This system uses a huge 5 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 30+ 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 7-14 days to ship out, depending on how many orders we have that week.
