In the 2006 model year, the GM Duramax LBZ turbocharged diesel V8 engine became available in models of the GMC Sierra until the end of the following year. Basically, it’s an upgraded version of the previous diesel V8, but with a more powerful computer able to generate incremental horsepower and torque. In fact, the 2006 -2007 Duramax LBZ produced a class-leading 360 horsepower and 650 lb·ft of torque.

The 6,599 cc (402.7 CID) LBZ Duramax V8 features 32 valves in aluminum cylinder heads bolted to an iron block. Bore and Stroke are close to square, at 4.06 inches x 3.90 inches, respectively.

There were a significant number of mechanical changes to the engine as well, including strengthening the bottom of the cylinder bores, installing more durable main bearings, casting more robust connecting rods, and raising maximum injection pressure from 23,000 psi to over 26,000 psi, replacing the existing injectors with all new seven hole designs that provide better fuel dispersion, a lower compression ratio to compensate for the improved fuel injection system, and a more efficient variable-geometry turbocharger for a smooth and immediate response with lower emissions.

If there’s one thing that a turbocharged diesel can’t get enough of, it’s intake air. A greater volume of intake air is compressed by the turbo, to which the engine’s computer responds by adding incremental fuel, the result being a burn that is more energetic, producing increased power at the wheels. A fast, simple, and inexpensive way to increase the power output of your LBZ engine Sierra is the installation of an AIRAID 202-289 MXP air intake system.

The entire 202-289 AIRAID MXP air intake system is designed with the use of extensive computer modeling to maintain proper mass air flow readings and calibration. The cold air dam addresses the shortcomings of the restrictive factory air box design, while incoming cold air from outside the vehicle is directed through a new air intake tube with a smooth, low-restriction interior surface thanks to its construction of cross-linked, high-density polyethylene. This MXP air intake system also includes fittings for the OEM mass air sensor and filter minder gauge, avoiding the need to recalibrate your truck’s ECU.

Housed inside the cold air dam is the AIRAID premium air filter that provides outstanding air flow and filtration through its reusable, dry, non-woven synthetic filter media. Maintenance of the 202-289 is simple: clean your AIRAID filter every 30,000 to 50,000 miles for normal driving, or more often if you’re driving off-road or in heavy dust conditions, with AIRAID 790-558 premium dry filter cleaning solution.

Installation of the 202-289 AIRAID MXP air intake system is fast and simple, with highly-detailed instructions. You need only a few basic hand tools and a couple of hours to increase the power and responsiveness of your LBZ-powered GMC Sierra 2500HD/3500HD truck.
