Fleetguard AF27684 Engine Air Filter | 2007.5–2023 Dodge Ram 6.7L Cummins
Description
Your engine can only perform as well as the air it breathes.
Every mile you drive, your air filter protects the turbocharger and engine from dust, dirt, sand, pollen, and other airborne contaminants. Even microscopic particles that make it past a poor-quality filter can damage the compressor wheel, wear piston rings, score cylinder walls, and reduce engine performance over time.
The Fleetguard AF27684 Engine Air Filter is engineered specifically for the 2007.5–2023 Dodge Ram 6.7L Cummins, delivering OEM-quality filtration while maintaining the airflow your turbocharger and engine were designed to receive. Developed by Fleetguard—the filtration company owned by Cummins—this filter provides the same level of protection trusted by the manufacturer.
Whether your truck is a daily driver, dedicated tow rig, work truck, or performance build, protecting your engine starts with clean air.
Features
- Genuine Fleetguard AF27684 engine air filter
- Direct replacement for the factory air filter
- High-efficiency filtration media
- Excellent airflow with low restriction
- OEM-quality fit and seal
- Protects turbocharger and engine components
- Designed specifically for the 6.7L Cummins air box
- Easy drop-in installation
- No modifications required
Why Your Air Filter Matters
Your turbocharger moves thousands of gallons of air every minute.
If contaminants make it through the filter, the turbocharger is the first component they encounter. Over time, abrasive particles can erode compressor blades and eventually reach the cylinders where they contribute to engine wear.
A quality air filter doesn't just improve filtration—it protects thousands of dollars in engine components.
That's why Cummins developed Fleetguard filters to balance two critical factors:
- Maximum airflow
- Maximum engine protection
Too much restriction can hurt performance, while inadequate filtration can shorten engine life. Fleetguard is engineered to deliver both.
Glacier Tech Tip
Many people assume that if an air filter "flows more air," it must be better.
In reality, every filter is a compromise between airflow and filtration efficiency.
Some high-flow performance filters achieve greater airflow by allowing larger particles to pass through the media. While this may slightly reduce restriction, it also increases the amount of contamination entering the turbocharger and engine.
For most daily driven, towing, and work trucks, proper filtration is far more valuable than chasing minimal airflow gains.
Why Choose Genuine Fleetguard?
Fleetguard isn't simply another aftermarket filter manufacturer.
Fleetguard filtration products are engineered alongside Cummins engines and are designed to meet the airflow, sealing, and filtration requirements established by the OEM.
Benefits include:
- Consistent filtration efficiency
- Proper sealing against the factory air box
- Excellent contaminant holding capacity
- Optimized airflow
- Proven long-term durability
Choosing a genuine Fleetguard filter means you're installing a filter designed specifically for the engine you're protecting.

Important Notes
- Genuine Fleetguard AF27684 replacement air filter.
- Direct drop-in replacement for the factory air box.
- Replace according to your maintenance schedule or sooner in dusty environments.
- Inspect the air box for debris during every filter change.
- Ensure the air filter is properly seated before reinstalling the air box lid.
Common Failure Point
One of the most overlooked causes of turbocharger wear is poor air filtration.
A damaged, improperly installed, or low-quality air filter can allow abrasive contaminants to enter the intake system. These particles first impact the turbocharger compressor wheel before continuing into the engine, where they accelerate wear on piston rings, cylinder walls, and other internal components.
Replacing your engine air filter on schedule is inexpensive insurance against costly engine and turbocharger repairs.
Complete Your Cummins Maintenance
Keep your Cummins protected from front to back by pairing your new air filter with other Fleetguard maintenance items:
- Fleetguard LF16035 Engine Oil Filter
- Fleetguard FS53000 Fuel Filter
- Fleetguard CV52001 CCV Filter
- Glacier Diesel Power Fuel Pressure Test Kits
- Glacier Diesel Power Fuel System Components
- Glacier Diesel Power Air Intake Upgrades
Routine maintenance with genuine Fleetguard filtration helps maximize engine life, maintain turbocharger performance, and keep your 6.7L Cummins operating the way Cummins intended.
