The K&N 69-4527TS is a Typhoon cold air intake built around a mandrel-bent aluminum intake tube and an oversized oiled cotton filter, and the manufacturer positions it as a replacement for the factory filter and intake tube on the 2012-2014 Cadillac CTS V6. Each system is paired with a washable, reusable High-Flow Air Filter featuring oiled cotton filter media. K&N's dyno chart for the 3.0L version shows an 11.48HP Increase, and the filter can be cleaned and reused rather than replaced like a disposable element. Choose this kit over a cheaper universal intake if you want a bolt-on tube matched to the CTS V6 with a documented, reusable filter and CARB paperwork. Searches for "2012 Cadillac CTS 3.0L cold air intake," "CTS V6 mandrel-bent aluminum intake," and "K&N 69-4527TS" will find this exact kit.
Fitment is listed for the 2012-2014 CTS V6 in 3.0L form, and K&N's 3.6L application page also lists this intake under the 2012 CTS 3.6L V6 gas category, so 3.6L owners should verify by VIN before ordering. The manufacturer's DIY section lists a 60-90 Minutes install time with a wrench, extension, flat blade screwdriver, and Allen wrench. One owner on a Cadillac forum who installed the kit on a 2013 CTS 3.6 Performance reported that the install took about 2 hours and every part fit exactly in place. Because sources differ on racing-only restrictions in some states, California and emissions-sensitive buyers should confirm the CARB EO D-269-49 status with the manufacturer.
The manufacturer's main product page lists this kit for the 2012-2014 CTS V6 3.0L, while its 2012 CTS 3.6L V6 application page also includes it. Confirm fitment for your specific engine with the manufacturer before ordering.
The manufacturer lists CARB EO number D-269-49 for this kit. Some sources note a racing-only restriction in select states, so confirm current status with the manufacturer for your state before installing.
The manufacturer rates this as a 60-90 minute job that needs only basic hand tools: a wrench, an extension, a flat blade screwdriver, and an Allen wrench. Owners on user forums report that a first-time install can take closer to two hours, so set aside an afternoon. Work with the stock airbox removed and keep the mass airflow sensor connection and crankcase vent hose routed as the instructions show, since those are the points most likely to cause a fit or check-engine issue. Follow the manufacturer's installation sheet for the correct order of steps.
