DESCRIPTION
Product Overview
- This dual-air filtration combo provides complete intake protection for 2015–2016 6.6L Duramax trucks, refreshing both your engine’s combustion intake and your passenger cabin HVAC airflow in a single package.
- Designed to balance powertrain efficiency with driver comfort, the high-flow engine air filter eliminates intake restriction for quick turbo response, while the activated carbon cabin filter traps road dust, seasonal pollen, and harsh exhaust odors. This 2-in-1 maintenance set is the perfect choice for truck owners looking to service both vital air pathways in one simple order.
Key Features
- Dual-path air filtration set addresses both engine combustion breathing and cabin HVAC air quality in a single convenient order.
- Precision-molded flexible seal creates a zero-gap compression fit inside the factory airbox to prevent unfiltered bypass air.
- Activated carbon cabin layer adsorbs harsh highway exhaust fumes, industrial odors, and seasonal pollen that standard mechanical filters miss.
- High-capacity engine air panel media offers superior dust-holding endurance for trucks working in agricultural, towing, or dusty job site conditions.
Replacement Interval
-
Inspect the engine air filter at 15,000 miles with replacement by 30,000 miles (15,000–20,000 miles under severe dusty conditions), and replace the cabin air filter every 12,000–15,000 miles (or annually). Because cabin filters collect dust and seasonal pollen quickly, servicing your interior filter on a regular annual cadence keeps your cab air clean regardless of engine service schedules.
FAQ
Q: Do both filters in this combo feature built-in seals for a direct drop-in fit?
A: Yes. Both the engine air filter and cabin air filter come with precision-molded perimeter seals engineered to match factory housing tolerances. They drop directly into your truck's original airboxes without requiring any modifications or additional sealing gaskets.
Q: Is this combo enough for a complete service or do I need the fluid filters too?
A: This covers the air filtration side — engine intake and cabin. You’ll still need fuel and oil filters separately to complete a full service. This combo is ideal when you’ve recently done your fluid filters but haven’t addressed the air filters.
Q: How do I access and install the cabin air filter on my truck?
A: The cabin air filter housing is located behind the glovebox. Simply drop the glovebox door by releasing the side retaining tabs, unclip the filter access cover, slide out the old panel, and insert the new filter with the printed airflow arrows pointing downward toward the blower motor.
Q: Will replacing a dirty cabin air filter eliminate musty A/C odors?
A: Yes. Over time, trapped moisture and dust on an old cabin filter can cause stale, musty smells when you turn on the air conditioning. Installing a fresh activated carbon filter neutralizes these trapped odors and keeps the cab air smelling clean.
Q: Adding fuel or oil filtration to this combo?
A: The Air, Cabin & Fuel Kit adds the TP3018 fuel filter. The Air, Cabin & Oil Kit adds the PF2232 oil filter instead.
