The Roto-fab High Flow G8 V8 intake system supplies 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”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 3.8” to 3.9” 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.
