The K&N 57-3093 is a 57 Series cold air intake for the 2016-2017 Cadillac ATS-V, which uses the 3.6L F/I twin-turbo V6, according to the manufacturer's listing. The system uses a black high-density cross-linked polyethylene intake tube paired with a red cotton-gauze panel filter, and the manufacturer positions it as a way to improve airflow over the factory intake. For a buyer comparing ATS-V 3.6 twin turbo cold air intakes, the key point is K&N's 50-state CARB status for this application, which many performance intakes on this engine do not have.
Before paying for this kit, weigh the gain against the stock setup. Owners on user forums say the ATS-V's factory intake already functions as a cold-air design, and one owner described K&N's kit as mainly replacing the passenger-side resonator box and filter while leaving the driver-side box in place, with gains that are hard to justify on power alone. K&N's own estimates for this kit are 34.43 hp at 5806 rpm and 36.5 lb-ft of torque. Treat those as estimates and compare them against your own logs before counting on them. The CARB Executive Order number is D-269-81.
Installation is generally a one-hour job with basic hand tools, based on K&N's general guidance for its kits, which lists ratchets, extensions, 10mm and 14mm sockets, and flat and Phillips screwdrivers. Expect to disconnect the mass airflow sensor, loosen the intake tube clamps, release the air filter housing, and move the MAF sensor onto the new tube's adapter. The 3.6L twin-turbo engine has both front and rear mass airflow sensors, so label each connector before you start. Searches for a 57-3093 install, a 2016 ATS-V CAI DIY, or a 3.6 twin turbo intake swap usually turn on this step.
The manufacturer lists this kit only for the 2016-2017 Cadillac ATS-V with the F/I twin-turbo 3.6L V6. Confirm your model and engine before ordering.
The manufacturer states the kit is legal for use in all 50 states under CARB EO D-269-81. K&N notes that a CARB EO number covers only the model years it lists, and that a decal showing the EO number must be displayed in the engine bay for smog inspections in states that follow California standards.
Owners on user forums report that the kit mainly replaces the passenger-side intake tube and filter, leaving the driver-side resonator box in place. Confirm the exact components with the manufacturer.
The manufacturer publishes estimated gains of 34.43 hp at 5806 rpm and 36.5 lb-ft. Owners on user forums question whether a cold-air swap delivers meaningful gains on this engine, so treat these numbers as estimates.
K&N's general instructions for its intake kits call for about an hour of work with ratchets, extensions, 10mm and 14mm sockets, an Allen key, and flat and Phillips screwdrivers. Start by disconnecting the negative battery cable, then unplug the mass airflow sensor and the crankcase vent line. Loosen the clamps at the throttle body and the air filter housing, remove the stock tube, and release the upper filter housing from its clips. Install the provided edge trim and gasket on the new housing and transfer the MAF sensor to the K&N adapter. Because the ATS-V uses two MAF sensors, check that both reconnect correctly before road testing. Plan for extra time on a first install, since the factory intake clips and the heat shield can take longer than the estimate.
