Let the Roto-fab Pontiac G8 High Flow upgrade kit give your current G8 system more power. As more of these cars are being modified, the requests for larger duct work have been more common. Over the past few years we have offered (in very limited special order quantities) a 102 mm intake which uses a 4 inch stainless steel inlet elbow measuring about 3.8 inch inside diameter.

This tube was then used with a 4 inch OD MAF sensor housing and the corresponding card style MAF sensor. Although performance levels increased, this combination was very expensive and time consuming to produce.

Another problem was the end user was responsible for supplying the MAF housing and then coupling all of the components together.
We are excited to announce the solution is here! The Roto-fab High Flow G8 V8 intake system solves aforementioned problems while supplying you with a system that has larger duct work from the filter all of the way to the throttle body. This system includes a new custom molded larger inlet elbow, 4 inch OD MAF sensor housing which accepts the card style MAF sensor and a larger air box adapter duct which is coupled by our oversize air filter. All of the correct silicone couplers are supplied as well. This system will now give you the same approximately 3.875 inch ID of the MAF sensor housing for the entire length of the duct work. Please keep in mind this style of MAF sensor does require tuning to your G8.
The Roto-fab Pontiac G8 high flow intake system is available as a complete unit or as an upgrade kit for those who already have our G8 V8 intake system.
The upgrade kit includes:
Inlet elbow, MAF sensor housing, air box adapter duct, (2) 4 inch- 4 1/4 inch silicone step hose couplers and (1) 4 inch-4 1/4 inch silicone step hump hose.
Please note this listing is for our upgrade kit only!
