Roto-fab has long been a recognized performance leader in the 5th and 6th Gen Camaro ZL1 CAI market. It is our goal to earn the same status with the CTS-V enthusiasts.

The Roto-fab third gen CTS-V CAI system features a powder coat aluminum air box custom formed and TIG welded to mate to the stock air inlet duct while hugging the CTS-V contours all the way around. The top perimeter effectively seals to the hood providing all of the advantages of a lid while maximizing air box volume and providing space for a huge filter. Our approach was to hand fabricate a custom air box with all the qualities we know are important, then relentlessly refine the design until we reached the exact fit we wanted.

The air box adapter bolts directly to the air box creating the MAF sensor housing on the engine side while transitioning to a huge 6” OD to accept the massive filter. The transition itself is molded to create a mounting flange on the exterior which mates to the air box to isolate the filter from engine bay heat while forming a “bell mouth” entry inside to increase air flow. Due to our rigid air box mounting system, we incorporate a silicone hump hose connector at the inlet elbow to absorb motor rock. To increase air velocity, the inlet elbow is custom molded with a slight taper throughout its length as it transitions down to the throttle body. To maximize air volume, we maintain a large ID on the inlet elbow then use silicone reducer to step down to the throttle body clamping diameter. The coupler clamps are stainless steel as are all of the mounting screws.

From start to finish, the Roto-fab CAI for the Gen 3 CTS-V is hand designed and built by US craftmen using high quality materials combined with American ingenuity. Thanks for taking the time to learn about our product.
