Duramax Diesel Cold-Air Intake Test (2017x34)

:

The LBZ Duramax Diesel engine in my 2006 Chevy Silverado 3500 dually is pretty much stock. The only mods the previous owner performed were a Magnaflow exhaust system and adding an Edge Products Evolution programmer, which I've been driving around set to Level 2, or tow mode. The engine runs great but is due for a new air filter so I decided to install a Jammer CAI, also from Edge Products, to see if it would indeed lower the temperature of the air coming into the turbocharger. My buddy Matt and I were able to install the system in under 30 minutes and test it out on a mild 83 degree (fahrenheit) day here in Georgia. I've got a couple more products from Edge to test but those will happen later on. For now, let's see what this CAI does.
