StaunchAuto Engine & Cabin Air Filter Combo for Traverse 2018–2026, Acadia 2017–2026 — High-flow engine & activated carbon cabin

StaunchAuto Engine & Cabin Air Filter Combo is a matched replacement set designed to restore engine breathing and cabin air quality for Chevrolet Traverse (2018–2026), GMC Acadia (2017–2026) and compatible GM SUVs.

This filter bundle pairs a high-flow engine air filter with a dual-layer cabin filter that uses activated carbon to reduce odors and trap fine particles. Both parts are engineered to match OEM fitments (see replace part numbers in the features) and to extend service life compared with standard paper filters. The combination addresses two common maintenance needs at once: preserving engine performance by keeping intake air clean, and improving in-cabin comfort by filtering dust, pollen and exhaust smells.

How does the engine filter support vehicle performance?

The StaunchAuto engine filter uses premium filter paper and a rigid ABS frame to maintain shape under airflow and heat. That helps ensure consistent filtration area, lower pressure drop, and protection of intake components from dust and debris.

• High-quality filter media captures dust and particulates before they reach the engine.
• Durable ABS frame resists deformation and keeps a tight seal in the airbox.
• Higher lifespan than many standard filters—replace every 6 months or 12,000 miles recommended.

What makes the cabin filter different from a basic pollen filter?

The cabin filter in this set features a coconut-shell activated carbon layer backed by a fine-particle filter to remove odors, gases and microscopic particles simultaneously. Its low-resistance design keeps HVAC airflow smooth while reducing blower noise and preventing reduced air volume.

• Activated carbon adsorption reduces odors and harmful gases from outside air.
• Double-layer filtration captures particulate matter with high efficiency.
• Low resistance structure minimizes HVAC noise and preserves airflow.

Will these replace my OEM part numbers and fit my vehicle?

Yes — the combo is built to replace common OEM part numbers for the listed models and model years. Double-check your specific vehicle year, make, model and engine to confirm compatibility; contact StaunchAuto within 24 hours if you encounter fitment issues.

• Engine filter replaces: CA12166, 23321606, JM2332, A3212C, 33-5056.
• Cabin filter replaces: CF11966, CP966, 13356914, 13508023, 22743911.
• Compatible with Traverse, Blazer, Acadia, Enclave, XT5 and XT6 models listed.

How often should I replace these filters and what savings can I expect?

StaunchAuto recommends replacing both filters every 6 months or 12,000 miles under normal driving conditions. Regular replacement helps avoid restricted airflow and potential engine strain, while improving cabin air comfort—small maintenance costs that can prevent more expensive repairs later on.

• Replace interval: approximately every 6 months or 12,000 miles.
• Regular changes help maintain engine efficiency and HVAC performance.
• Cost-effective compared with potential downstream repairs from clogged filters.

Who is this for? The StaunchAuto Engine & Cabin Air Filter Combo is for owners of compatible GM SUVs—Chevrolet Traverse and Blazer, GMC Acadia, Buick Enclave, and Cadillac XT5/XT6—who want OEM-equivalent fit, improved cabin comfort, and a durable engine air filter. It’s suited for routine DIY maintenance or professional service bays looking for a matched filter set that saves time and restores both engine and HVAC performance.
