StaunchAuto Engine & Cabin Air Filter Combo for 2019–2026 Silverado & Sierra 1500 — Reinforced Engine Filter, Activated-Carbon Cab

StaunchAuto’s Engine & Cabin Air Filter Combo replaces both the engine intake and passenger-cabin filters for compatible 2019–2026 Silverado and Sierra 1500-series trucks, delivering cleaner engine airflow and fresher in-cabin air.

Keep your GM truck running smoothly and occupants breathing easier with a matched pair of replacement filters engineered for modern Silverado and Sierra models. This combo bundles a rugged engine air filter built from reinforced filter paper and ABS framing together with a dual-layer cabin filter that uses coconut-shell activated carbon to reduce odors while trapping fine particles. The set is designed specifically for gasoline engines listed below — verify fitment for your exact year and engine type before ordering.

Which models and engines will this filter combo fit?

This kit fits a wide range of Chevrolet and GMC trucks and SUVs from model years 2019 through 2026 when equipped with the specified gasoline engines. It is not intended for 6.6L diesel applications — always confirm the engine type and model year.

• Chevrolet Silverado 1500 (2019–2026) and Silverado 1500 LTD (2022)
• Silverado 2500HD & 3500HD 6.6L gasoline models (2020–2026 for some years; not for diesel)
• Chevrolet Suburban, Suburban 3500, Tahoe, Escalade, Escalade ESV, Yukon, Yukon XL (select 2021–2026 models)
• GMC Sierra 1500 (2019–2026), Sierra 1500 Limited (2022), Sierra 2500/3500 HD gasoline models, and compatible Yukon/Yukon XL/Denali variants

How does the engine air filter improve performance?

The engine filter uses multi-layer media and a reinforced ABS frame to resist collapse and last longer than many standard filters. Cleaner intake air helps the engine run more efficiently and reduces the risk of debris-driven wear on internal components.

• High-quality pleated filter paper captures dust and large particulates
• Sturdy ABS frame resists deformation under airflow pressure
• Extended service life compared with basic single-layer filters
• Direct replacement for CA12405 specification fitment

What makes the cabin filter effective for occupants?

The cabin air filter combines a mechanical filter layer with coconut-shell activated carbon to trap particles and adsorb odors and some gases. The low-resistance design maintains smooth HVAC airflow and minimizes blower noise while improving in-cab air quality.

• Dual-layer filtration captures pollen, dust, and fine particulates
• Activated carbon layer helps reduce odors and volatile compounds
• Low-resistance structure preserves air volume and reduces HVAC rattle
• Drop-in replacement for CF11966 cabin filter specification

When should I replace these filters and what are the benefits?

Replace both filters about every 6 months or 12,000 miles under normal driving to keep airflow and filtration effective. Regular changes prevent debris buildup that can restrict airflow, reduce HVAC performance, and accelerate engine wear.

• Recommended service interval: ~6 months or 12,000 miles
• Helps maintain peak HVAC output and quieter operation
• Protects engine from abrasive particles and potential premature wear
• Small recurring cost that can prevent larger repair bills over time
