This is our 5" Cold Air Intake system for 03-07 Cummins 5.9, this is the biggest system on the market! 

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 35+ Horsepower!


This system is made for stock sensor calibration. Meaning this system works perfect with no check engine lights, no matter if your truck is stock, or highly modified

Has a bolt in heat shield that is vary 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 6-14 days to ship out, depending on how many orders we have that week.

  • Any promo codes for 4th gen Dodge intakes

    We can do a free T shirt, but other than that we dont have any sales right now. Just include a note at checkout for free shirt and list the size you need. Thanks

  • Which filter is the blue one shown in the pic? I like the candy blue but would want a blue filter to match. Is this intake better than the sinister diesel intake you offer? Do you have any coupon codes for the intakes for a 2012 Cummins?

    It is the amsoil filter. Yes it is better then the sinister as the sinister is only 4" and has no heat shield. I dont have any sale right at this time, but we do from time to time
