2008 GMC Sierra - Fantastic Four - Tech

The kit contains an additional hanger that was added next to the spare tire.

Since the Gibson muffler was more compact than the huge factory one it replaced, installation was easy. Tony was able to position the entire system in just a few minutes.

Once he was happy with the fit, Tony clamped the joints and added a tack weld for protection.

Here's the entire XDI intake from True Flow, it has everything you need, down to a zip tie.

Tony popped off the engine cover and loosened the hose clamp from the factory intake tube.

Next, he routed the new intake tube under the coolant hose and attached it loosely to the throttle body. The second silicone connector was attached to the MAF sensor.

To smooth out the airflow, True Flow's filter flows inside out, so you're looking at the clean side of the filter. An O-ring seals the canister, so air is drawn in only through the foam filter element.

The canister was attached to the intake with a hose clamp and positioned to draw air in through a hole in the passenger fender. Next, the engine cover was set back in place and the intake was done.

Here's the crown jewel of this month's fantastic four: bonspeed wheels and continental tires.
