The Roto-Fab G8 air intake is a cold air system is designed to maximize performance and air flow for the 2008 - 2009 Pontiac G8. The system includes an air box that is a one-piece molded unit that extends downward and outboard of the frame rail. This is crucial since the radiator fans fill the engine compartment with extremely hot air. The box was designed to maximize filter size while creating good alignment for the MAF sensor and the duct work to the throttle body. The open top combined with the hood seal allows the most air possible to all areas of the filter while maintaining a barrier against harmful engine and radiator heat. Also, the exposed filter looks very impressive when you pop your hood.
To get the cold air moving there is a transition tube that couples the air filter to the MAF sensor. It features a mounting flange with a velocity stack design to maximize the air flow to the MAF sensor. The transition tube mounts solidly to the air box using five stainless steel screws that engage the molded-in 10-32 brass inserts. The transition mounts to the MAF sensor with a high gloss silicone hose. This unique design allows for a huge S & B high flow air filter with a 6 inch mounting flange and 6 inch filter length. On the throttle body side of the MAF sensor, a silicone hump hose absorbs the engine movement. Coupled to the opposite end of the hump hose, is a custom molded inlet duct with a large, gentle radius that keeps the air moving smoothly.
