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

StaunchAuto's Engine & Cabin Air Filter Combo provides vehicle-specific filtration for Chevrolet Traverse (2018–2026) and GMC Acadia (2017–2026), combining durable engine protection with activated-carbon cabin odor control.

If you drive a Traverse, Blazer, Acadia, Enclave, XT5 or XT6 in the listed years, this matched pair replaces worn intake and interior filters with parts engineered to fit exact factory dimensions. The set pairs a reinforced engine filter made from multi-layer media and an activated-carbon cabin filter to reduce particles, dust and common odors while promoting efficient airflow for HVAC comfort.

How does the engine filter protect my vehicle?

The engine filter uses dense, multi-layer filter paper supported by a rigid ABS frame to trap dust, pollen and road debris before they reach the intake. Its construction aims to extend service life compared with standard disposable filters and help the engine breathe more cleanly.

• Replaces part numbers CA12166, 23321606, JM2332, A3212C, 33-5056
• Reinforced ABS frame for shape retention under load
• Multi-layer media captures fine particles and larger contaminants
• Designed for a longer service interval versus basic filters

Will the cabin filter improve in-car air quality and comfort?

The cabin filter includes a coconut-shell activated carbon layer plus a secondary filtration mesh to adsorb odors, fumes and many airborne contaminants. It is constructed to keep airflow smooth and quiet, minimizing HVAC noise while maintaining effective filtration.

• Activated carbon layer reduces odors and transient gases
• Double-layer media achieves high particle capture efficiency
• Low-resistance design preserves HVAC airflow and lowers noise
• Replacement part references CF11966, CP966, 13356914, 13508023, 22743911

How often should I replace these filters and what are the savings?

StaunchAuto recommends changing both filters about every six months or 12,000 miles under typical driving conditions. Regular replacement prevents accumulated debris from restricting airflow or reducing filtration performance, which can protect HVAC function and reduce the risk of engine problems tied to contaminated air.

• Suggested interval: ~6 months or 12,000 miles
• Timely changes maintain HVAC efficiency and cabin comfort
• Preventative maintenance can avoid more expensive engine or ventilation repairs
• Cost-effective compared with OEM single-piece replacements

Which vehicles and part numbers does this combo fit?

This combo is tailored to specific GM models and years—double-check your vehicle’s year and engine type before purchase to ensure fit. The listing covers several model years across Chevrolet, GMC, Buick and Cadillac; part number references help verify compatibility.

• Chevrolet Traverse: 2018–2026 compatible years
• Chevrolet Blazer: 2019–2026 compatible years
• GMC Acadia: 2017–2026 compatible years
• Buick Enclave, Cadillac XT5/XT6: applicable model years included
