The AIRAID cold air dam improves power and drivability at all engine speeds.
Although GM performance car engines have most recently carried LS designations, Chevrolet, Cadillac and GMC truck and SUV engines built on this architecture have been marketed under the Vortec name. Early on, the Vortec engines were built around iron cylinder blocks and were offered in smaller displacements than car engines, though that changed quickly.
The AIRAID cold air dam virtually seals off the air filter from the hot underhood area.
In 2005, GM upgraded what was known as the Gen III small block engine to a new Gen IV specification, which included a new casting method and the facilities to add modern engine management strategies. Despite the differences between the Gen III and Gen IV, all LS/Vortec engines share some common features. These include the 4.40 inch bore centers, which they share with the original Chevrolet small block, six bolt main bearing caps, and cylinder heads with four bolts per cylinder.
In just two model years, 2007 and 2008, four different engines were offered across seven different models of GM trucks and SUVs. They were: the 4.8L, the smallest-displacement Vortec engine which featured an iron block and aluminum heads. The 5.3L, which was the most popular Vortec truck engine, it was, in essence, a 4.8L with a longer stroke and shared the iron block and aluminum cylinder blocks. The 6.0L was installed primarily in ¾ ton and one ton trucks, the 6.0L was available with an iron engine block with aluminum heads or an aluminum block with aluminum heads named the VortecMax. The 6.2L engine is manufactured with an aluminum block and heads, and incorporates variable valve timing. The 6.2L is used primarily as a high-performance engine for the Cadillac Escalade and GMC Yukon Denali.
Despite the relative complexity of the various engines available, if you own a Cadillac, Chevrolet, or GMC from 2007 or 2008, AIRAID has a singular solution in the cold air dam (CAD) performance air intake, part number 202-197. They are designed to provide an increased flow of cooler air from outside of the vehicle for your Vortec V8. With more incoming air available, the ECU adds more fuel to match, and the engine produces more horsepower and torque.
No need to move or remove any other components other than the stock intake, as the cold air dam retains the original location of the air filter. The panels mount in the factory air box location and utilize any existing factory cold air inlet ducts, while supplementing air flow with additional cold air passages to the filter.
Another critical factor is the nine-inch tapered conical AIRAID premium air filter that is housed inside the CAD, providing both outstanding air flow and filtration to your Vortec engine. The filter utilizes a reusable, dry, non-woven synthetic filter media. To maintain performance, clean your AIRAID filter every 30,000 to 50,000 miles, depending on driving conditions. The best and easiest way is with the AIRAID premium dry filter cleaning solution 790-558.
Incoming cold air from outside the vehicle is directed through the air filters and into a new air intake tube with a smooth, low-restriction inner surface due to its construction of cross-linked, high-density polyethylene. Installation of the 202-197 cold air dam is simple, with easy-to-follow instructions. You need only a few tools most everyone has in their garage and around 90 minutes to increase the power and responsiveness of your Vortec engine. And something not all cold air intake system manufacturers can claim: the 202-197 AIRAID CAD air intake system is street legal in all US states, CARB EO Number: D-609-18.
The 202-197 cold air dam is backed by AIRAID’s “No Hassle” Lifetime Warranty.
