This system is made for Stock MAF (Mass Air Flow Sensor) calibration. This system does NOT Require Custom tuning to calibrate the MAF sensor.
This is our highest flowing full 5" Cold Air Intake system for 01-04.5 LB7 Duramax, this system is full aluminum tubing from filter to turbo, comes with 3.5" turbo horn with MAF Sensor Mounting Pad, Stock MAF wire harness will reach new location just fine.
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!
Has a bolt in heat shield that is vary well sealed to keep underhood temps away from the air 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 10-14 days to ship out, depending on how many orders we are working on building.
Has RPI Logo on top of heat shield lid, we can do Custom lids that say: LB7, 6.6, or other options.
QUESTIONS & ANSWERSAsk a Question
where dose the mass airflow sensor go?
This kit comes with a 3.5" horn and on the horn the maf sensor is mounted with this system, it does not require any modifications or adjustments, just bolt on and go.
Is there any performance difference between this one and the stage 2?
Yes because the stage 3 comes with turbo horn, so its around 13hp gain more than stage 2
