The K&N 63-3084 Air Intake fits some Cadillac ATS, and Cadillac CTS models. See vehicle applications link for details.
The K&N 63-3084 AirCharger air intake system replaces the restrictive factory air filter and air intake housing on some Cadillac ATS and CTS models. K&N air intakes are designed to dramatically reduce air intake restriction as well as smooth and straighten air flow. This allows your engine to inhale a larger amount of air than the factory air filter assembly. More air means more usable power and acceleration throughout the engine’s RPM range. The air intake comes with a chrome topped K&N high-flow air filter and a heat shield that installs into the original air box space. Air is directed through an aerodynamically engineered intake tube into the engine’s throttle body for a guaranteed power gain. The tube accommodates the factory mass air sensor and crank case vent hose while the heat shield adapts the secondary air hose (where equipped) to a secondary air filter as well. The oversized cone shaped air filter can be used for up to 100,000 miles before servicing is needed depending on driving conditions. This air intake is relatively easy to install, usually in 90 minutes or less using your vehicle’s existing factory mounting points.

Amazing product. Lets the motor breathe while also giving a deeper growl to the exhaust. I also have a cat back on my 14' ATS and with this added its a perfect combo. Quick and easy installation had it done in just over a half hour. Highly recommend.

I've installed K&N systems on several of my cars in the past and I've been waiting for this product to be available for my Cadillac ATS for sometime now and I've not been disappointed....better mileage, noticeable power increase, and great sound.

Great addon to the Cadillac 3.6L LFX engine. This wasn't available when I got my 2014 CTS, but I recently checked again and finally K&N offered this Performance Intake Kit. I bought it, and it shipped quickly. It took me and my dad about 1.5 hours to install. There was only 1 difficult part, with the rubber mounting bracket, it was very hard to tighten, so we ended up removing the intake, tightening the rubber bracket first, then reconnecting the other side to the intake as we put it back in. Performance is definitely increased. There is a notable difference in the engine sound also, it is much more throaty but it could just be inside the car since the CTS has microphones in the engine compartment and pipes that noise into the car stereo. You hear more since it is not a closed box like the stock air intake. This intake will let the engine breath harder and go faster, bottom line.

Not that I want anyone to have more power than my 2013 Cadillac ATS Premium AWD 3.6L, but this air intake is awesome. It was a bit of a challenge to intall using the supplied mounting adapters, but it was worth it. NOTE: not all vehicles have the air pump tube with secondary air filter, so you pay for something that will not be used. Thanks K&N for allowing me to be the first 2013 Cadillac ATS 3.6L to review this product. Can't wait to take it to local dyno shop to see how the gains compare at aptitude that isn't the 2014 CTS 3.6L.
