Regular price $349.99 $329.99 Sale

This is our 5" Cold Air Intake system for 01-04.5 LB7 Duramax, 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 when used with a ported or 3.5" turbo horn, adds around 22+ Horsepower with stock horn, but will perform better with high flow 3.5" turbo horn, 

 

    

This system is made for stock MAF (Mass Air Flow Sensor) calibration. Meaning this system works perfect with no check engine lights, no matter if your truck is stock, or highly modified. NO EFI Live Required!

Has a bolt in heat shield that is vary well sealed to keep underhood temps away from the large 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 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. If you want a color we do not list just let us know.

Has RPI Logo on top of heat shield lid, we can do Custom lids that say: LB7, 6.6, or other options. For custom cutouts on lid it is an extra $25
