K&N Engine Air Filter for Dodge Ram Trucks KNX-2247 — 24,000-Mile Extended Life

K&N's KNX-2247 is a long-life engine air filter engineered to protect and support performance on compatible Dodge Ram trucks for up to 24,000 miles between replacements.

Engine air filtration matters for longevity and steady performance. The KNX-2247 from K&N swaps into the factory air box and uses a specially treated filter media that balances filtration efficiency with airflow. Compared with conventional disposable filters, this Advantage Plus unit is built to stretch service intervals while meeting or surpassing original equipment standards.

How does this filter protect my Ram's engine?

The KNX-2247 captures airborne particles before they reach the intake while maintaining consistent airflow to the engine. Its premium media is treated to increase particle capture efficiency without creating excessive restriction.

• Up to 99.5% efficiency in trapping damaging debris
• Multi-layer treated media suited for road and highway driving
• Form-fit design to seat in the factory air box with no modification

Will installing this filter affect performance or fuel economy?

This K&N filter is designed to preserve or modestly improve airflow compared with standard paper elements, which can help the engine breathe with less resistance. Any performance gains are application-dependent and modest; the primary benefit is consistent airflow over a longer service life.

• Engine-friendly airflow profile maintained
• Designed to meet OEM airflow and fitment criteria
• May support smoother throttle response under typical driving

How often does the KNX-2247 need to be replaced and how easy is installation?

K&N specifies a 24,000-mile replacement interval under normal highway driving—about twice the life of many standard disposable filters. Installation is straightforward: open the factory air box, remove the old element, and drop in the K&N unit; no tools or airbox modifications are normally required.

• Replacement interval: up to 24,000 miles under typical conditions
• Quick swap into factory air box—usually minutes to install
• Suitable for routine maintenance at service intervals

Which Dodge Ram models and engines will this filter fit?

The KNX-2247 covers many Ram model years and engine configurations—V6, V8 and V10—across 1500, 2500, 3500, 4500 and 5500 series trucks. Confirm fitment for your specific model year and powertrain before purchase.

• Covers wide range: 2002–2026 model years across multiple Ram series
• Compatible with several factory intake housings—check part cross-reference
• Designed to match OEM dimensional and sealing requirements

Who is this for? K&N's KNX-2247 is aimed at Dodge Ram owners who want a higher-capacity, longer-life replacement for stock paper air filters—drivers who prefer reduced maintenance frequency without altering the factory airbox. It's a practical option for daily drivers, work trucks, and those who value proven filtration technology and straightforward, tool-free installation. Before ordering, verify compatibility with your Ram's model year and engine to ensure proper fit and performance.
