Roto-Fab Cold Air Intake for the 2016-2018 Cadillac CTS-V


Official Roto-Fab Press Release


The Roto-Fab CAI system for the 2016-2018 Cadillac CTS-V is here! After months of development, we’re excited to release a high quality, “no tune required” cold air intake system for Gen 3 CTS-V owners. Chassis dyno test results from three very reputable shops showed gains ranging from 20+ HP up to 30+ HP with the Roto-Fab CAI alone on otherwise stock cars. Gains with a tune were even more impressive! Now CTS-V owners can enjoy great performance, sound, and appearance out of a single bolt-in product.

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 make 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 out 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 alight taper throughout it’s length as is 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 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 craftsman using high quality materials combined with American ingenuity. That’s for taking the time to learn about our product.

JDP Motorsports Dyno Testing


On behalf of Roto-Fab, JDP Motorsports performed in-house dyno testing on the new system. We saw gains of up to +35 WHP +24 WTQ from the Roto-Fab, LLC Cold Air Intake on an otherwise stock 2018 Cadillac CTS-V. We've come to expect premium quality and performance from the Roto-Fab brand, and this intake system meets and exceeds our expectations.
