COCOAUTO Engine & Cabin Air Filter Kit for Cadillac XT5/XT6 (2017–2026) — High-Flow Engine Filter + Activated-Carbon Cabin Filter

COCOAUTO's Engine Cabin Air Filter Kit delivers a matched engine air filter and activated-carbon cabin filter designed to restore airflow, reduce odors, and help protect your vehicle's engine and HVAC system.

This 2-in-1 kit is built for owners of Cadillac XT5 and XT6 models (and compatible GM SUVs listed below) who want a single purchase that covers both engine intake and cabin ventilation maintenance. Each kit includes one high-flow engine air filter and one activated-carbon cabin air filter manufactured to near-OEM specifications to fit factory housings and install quickly with basic hand tools. Replace both filters at the recommended intervals to maintain performance, reduce interior smells, and protect components from excessive dirt and particulates.

Which vehicles and model years will these filters fit?

The COCOAUTO kit is matched to a range of GM crossovers and SUVs. It covers multiple model years and uses common part cross-references to match factory replacements.

• Cadillac XT5: 2017–2026 and Cadillac XT6: 2020–2025.
• Also compatible with Chevy Traverse, GMC Acadia, and Buick Enclave across 2018–2026 ranges, and Blazer 2019–2025 (not for Blazer EV).
• Check the included replacement numbers (engine and cabin cross-references) against your OEM part to confirm fit before purchase.

How do these two filters improve vehicle performance and comfort?

The engine and cabin filters address separate systems but work together to maintain overall vehicle health. The engine air filter helps ensure cleaner intake air to maintain fuel economy and consistent throttle response, while the activated-carbon cabin filter reduces odors and particulate entering the passenger compartment.

• Engine filter: higher airflow design to help preserve engine efficiency and responsiveness.
• Cabin filter: activated carbon media traps odors, pollen, dust, and exhaust particles.
• Replacing both filters prevents clogged airflow that can stress HVAC blowers and engine components.

What are the replacement intervals and maintenance tips?

Follow routine replacement to keep systems working as intended. Typical guidance is a yearly service, but driving conditions determine frequency.

• Suggested interval: every 12 months or 12,000 miles under normal conditions.
• Increase service frequency in dusty, coastal, or high-pollen environments.
• Use Amazon’s compatibility tool or verify OEM numbers (listed below) before ordering to avoid wrong-fit purchases.

What do I get in the box and how easy is installation?

This kit contains two filters matched to common OEM specifications, packaged for immediate installation. Most owners complete the swap with basic tools in roughly ten minutes per filter.

• Included: 1 activated-carbon cabin air filter and 1 high-flow engine air filter.
• Near-OEM fitment means no trimming or modification for compatible vehicles.
• Installation time: about 10 minutes for routine filter replacement; consult vehicle manual if unsure.

Replacement part references included with the kit help confirm compatibility: engine replacements (23321606, CA12166, CF11966, A3212C) and cabin references (13356916, 13508023, CF196, CAF4211C, CF1185, CAF1904P, 23135671, CAF1904M, 23393247, CAF4211). These cross-references make it simple to match your OEM numbers before ordering.

Who is this for: The COCOAUTO Engine Cabin Air Filter Kit is intended for Cadillac XT5 and XT6 owners, and drivers of compatible GM SUVs, who prefer a single, convenient purchase to service both engine intake and cabin ventilation. It's a good choice for DIY vehicle maintainers who want near-OEM fit, activated-carbon odor control, and an affordable way to keep HVAC airflow and engine performance within factory expectations. Always verify fit using your vehicle year and OEM part numbers before installing.
