StaunchAuto Engine & Cabin Air Filter Combo — Chevrolet Equinox 2018–2026, ABS-frame engine & activated-carbon cabin

This StaunchAuto combo replaces the engine air filter (CA12260) and cabin air filter (CF11966) for Chevrolet Equinox and compatible GMC Terrain models from 2018–2026, delivering longer filter life and improved in-cabin air quality.

If you own a 2018–2026 Chevrolet Equinox 1.5L or the listed Terrain/Equinox 2.0L model years, this matched pair gives you both engine protection and safer, fresher cabin air in one purchase. StaunchAuto built the engine filter with durable ABS framing and high-grade filter media for extended service life, while the cabin filter uses coconut-shell activated carbon and a double-layer design to trap odors, gases, and fine particles.

How will the engine filter protect my vehicle?

The engine air filter is designed to capture dust, road grit, and airborne contaminants before they reach sensitive engine components. Using multi-layer filter media and a rigid ABS frame, it keeps airflow steady while reducing particle ingress that can cause wear or reduce efficiency.

• Replaces OE-equivalent CA12260 for correct fit and airflow
• High-quality filter paper for better dust capture
• Sturdy ABS frame to resist deformation and extend service life
• Recommended replacement interval: about every 6 months or 12,000 miles

What makes the cabin filter different from basic replacements?

The StaunchAuto cabin filter couples a fine particulate layer with coconut-shell activated carbon to remove odors and adsorb harmful gases while filtering pollen and dust. Its double-layer construction increases filtration efficiency without blocking airflow, maintaining comfortable ventilation and reducing HVAC noise.

• OEM-style fit matching CF11966 dimensions
• Coconut shell activated carbon for odor and gas adsorption
• Double-layer media achieving high particle capture efficiency
• Low resistance design keeps blower noise down and airflow steady

Will these filters affect fuel economy or HVAC performance?

Properly functioning filters support efficient engine breathing and consistent HVAC airflow, which can help the vehicle operate as intended. The engine filter balances filtration with airflow to avoid undue restriction, while the cabin filter’s low-resistance construction preserves fan performance and reduces rattles.

• Engine filter maintains steady intake airflow for combustion efficiency
• Cabin filter reduces HVAC strain by minimizing airflow resistance
• Both items help avoid performance losses caused by clogged aftermarket filters
• Regular replacement prevents buildup that could impact systems over time

How easy is installation and which vehicles are covered?

Installation is straightforward for anyone familiar with basic filter changes; both parts are form-fit replacements for their respective OE numbers. They’re supplied to fit the listed Chevrolet Equinox and GMC Terrain engine options and model years, so you won’t need modification or special tools beyond common hand tools.

• Compatible models: Equinox 1.5L (2018–2026); Equinox 2.0L (2018–2020)
• Also fits GMC Terrain 1.5L (2018–2026) and Terrain 2.0L (2018–2021)
• Engine air filter replaces CA12260; cabin filter replaces CF11966
• Designed for simple swap-in installation using standard procedures

Who is this for: Drivers who own compatible Chevrolet Equinox or GMC Terrain models and want a cost-effective, OEM-fit filter pair that extends service life and improves in-cabin comfort. This combo is suited for routine maintenance buyers, DIYers replacing filters at home, and fleet managers seeking consistent filter performance without premium dealer pricing. Replace every six months or about 12,000 miles to maintain airflow, reduce odors, and help protect your engine and HVAC system from accumulated debris.
