The K&N 63-3096 is a cold-air intake kit for the supercharged 6.2L V8 in the Cadillac CTS-V. It replaces the factory airbox and small filter with a larger conical cotton-gauze element, plus a black intake tube and heat shield that use the factory mounting points. The manufacturer estimates roughly 50 HP and 40 lb-ft of gain, but some owners on user forums argue the stock intake tube already flows well, so the real benefit depends on the rest of your setup. The lifetime warranty and a washable filter rated for up to 100,000 miles help offset the price over the long run.
Fitment listings disagree on the model years, with some showing 2016-2019 and others 2016-2017, so confirm your VIN against the manufacturer before ordering. The manufacturer's instructions put a typical install at about an hour and call for common metric and Torx tools. Disconnecting the negative battery cable erases stored memory settings, so note your radio and anti-theft codes first. Searchers looking for a 2016 CTS-V supercharged V8 cold air intake, CTS-V airbox delete, K&N AirCharger install, or oiled cotton gauze CTS-V filter will find this kit's details below.
The manufacturer's install sheet recommends that customers do not discard the factory air intake, so store it after removal.
The manufacturer states the filter is washable and reusable and can run up to 100,000 miles before service is required, depending on driving conditions.
Per the manufacturer's install sheet, the stock mass air sensor is removed from the old airbox and installed on the new setup, and a mass air sensor adapter is included in the parts list.
The manufacturer lists this kit as not legal for sale or use in California on any pollution-controlled motor vehicle.
The manufacturer rates a typical installation at around an hour. The install sheet lists a 10mm wrench, 5/8" wrench, 3mm and 4mm Allen keys, a T20 Torx bit, and a flat-blade screwdriver. Start by disconnecting the negative battery cable, then lift off the decorative engine cover, unhook the radiator hose mount and crankcase vent hose, loosen the clamps on the stock tube, and pull the air cleaner from its grommets. Install the heat shield and filter adapter on the factory points, then connect the new tube, vent hose, and filter with the supplied clamps. Watch for the radio anti-theft code after reconnecting the battery, and use only the hardware provided in the kit.
