2006 GMC 2500 Crew Cab - Diesel Pow Pow Power

Apparently, someone wasn't paying attention while packing the aFe Stage 2 intake, because the included nylon spacers were way too small. In this photo, the hardware was snugged in place and held the MAF sensor, but the spacers were there to prevent the installer from over tightening the screw. Being the premiere shop it is, NorCal Truck had other items in stock for us to remedy the situation.

Using silicone adapters, Nic laid the new intake piping into position. In this picture, you can also see the supplied lower metal shield that acts as the scoop, holding the fresh outside air where it's needed most.

AFE's huge filter was the next thing to install.

The fresh intake was finished off with this diamond-plate appearing cover. It was held in place with stainless button-head bolts, and it seals off the filter from drawing any under-hood air into the engine.

Nic spread the components across the shop floor to take account for all of MBRP's supplied exhaust parts. It was also a great time for us to get a shot of all the pieces together before they went into the GMC.

A liberal dosage of penetrating oil was sprayed on the stock nuts and bolts to make them easier to remove. Between that and the truck's low mileage, it wasn't necessary to break out the big guns. Simple handtools were used to show the ease of the installation.

With the stock exhaust gone from under the 2500, the MBRP slip joint was the first part to go on.

Since the girls all think Nic is a good-looking dude, we slipped in a picture of him placing the extension pipe into the slip joint.

MBRP's polished stainless muffler was next to go on. It was set up per the instructions and ensured the inner vanes faced the same direction as the flow of air exiting.
