DESCRIPTION
Product Overview
- This dual-air filtration combo provides complete intake protection for 2020–2025 6.6L Duramax trucks, refreshing both your engine’s intake airflow and passenger cabin HVAC system in a single package.
- Tailored for heavy-duty towing, off-road jobsites, and daily highway driving, the high-flow engine air filter minimizes airbox restriction to support responsive turbocharger boost, while the multi-layer cabin air filter captures airborne dust, pollen, and road fumes before they enter the cab. It is the ideal 2-in-1 maintenance set for truck owners who service liquid filters on an independent schedule and want both air pathways updated in one simple order.
Key Features
- Industrial-grade filter media effectively traps fine silica, road dust, and airborne debris to protect engine intake efficiency.
- High-tensile silicone perimeter seal creates a tight compression fit inside the airbox that stays securely seated during heavy chassis flex and off-road vibration.
- Electrostatic cabin media holds a consistent charge to attract and hold fine dust, pollen, and diesel exhaust particles for cleaner cab air.
- Optimized pleat spacing allows deep debris storage across the entire surface area without restricting air volume to your HVAC vents.
- Comprehensive 2-in-1 combo streamlines your service routine by allowing you to update both engine intake and interior climate air filters in a single maintenance session.
Replacement Interval
-
Inspect the engine air filter at 15,000 miles with replacement by 30,000 miles (15,000–20,000 miles under severe duty), and replace the cabin air filter every 12,000–15,000 miles (or annually). Because modern automatic climate control systems rely on unrestricted airflow to maintain cabin temperatures, keeping a fresh cabin filter installed prevents extra strain on the blower motor and maintains strong vent airflow year-round.
FAQ
Q: Will installing these filters interfere with sensitive intake sensors or trigger a Check Engine light?
A: No. Both filters are precision-molded to factory dimensions, ensuring an airtight seal that maintains normal intake airflow and pressure readings without disrupting mass airflow (MAF) sensors or setting off diagnostic codes.
Q: Can I blow out the engine air filter with compressed air to extend its life between changes?
A: We advise against using high-pressure compressed air. While it removes large debris, the air pressure can tear or expand the micro-pleats, compromising filtration accuracy. Gentle tapping to dislodge loose dirt is fine, but replacement is recommended once the media is loaded.
Q: Will driving in heavy rain or humid conditions damage or saturate the engine air filter paper?
A: No. The filter media utilizes a moisture-resistant synthetic blend that resists water saturation and prevents the pleats from collapsing or tearing during wet weather or heavy rain highway driving.
Q: Does the electrostatic charge in the cabin filter wear out over time?
A: No. The electrostatic charge is permanently infused into the synthetic fibers during manufacturing. It remains active throughout the filter’s service life, continuously attracting fine dust and particles without degrading from humidity or age.
Q: Ready to add the fluid filters for a complete 2020+ service?
A: The Air, Cabin & Oil Kit adds the PF26 oil filter. For full four-filter coverage, use the Full Maintenance Kit.
