Which Ram models and years will this KAX filter fit?

The CA10261 was manufactured to match the original equipment specifications for many heavy-duty Ram trucks and related models. Check fitment carefully because it covers multiple engine options and production years.

• Ram 2500 and 3500: selected 2007–2025 diesel and gas model years listed in the product specs
• Ram 4500 and 5500: compatible years include 2008–2013, 2019–2025 depending on engine
• Other compatibilities: Dodge Ram older 6.7T models and Sterling Truck Bullet series 2008–2010

How does this filter improve engine protection and performance?

KAX uses a high-performance oiled cotton gauze plus embossed paper media to capture more particulates while keeping adequate airflow. That combination helps reduce engine wear and maintain steady throttle response without creating excessive restriction.

• 99.9% filtration efficiency for fine particles that harm turbochargers and cylinders
• High dust-holding capacity to extend service intervals up to approximately 20,000 miles
• Engineered media and manufacturing stability to preserve shape and sealing under heat and vibration

Is this filter reusable or washable, and what maintenance does it need?

The CA10261 is a replace-only filter — it is not washable or reusable. The design emphasizes dependable single-service life and reliable sealing, so routine replacement is the recommended maintenance rather than cleaning.

• Not washable; replace per mileage or manufacturer guidance
• Typical suggested interval up to 20K miles depending on driving conditions
• Sold as a single boxed unit with dimensions to confirm fit before installation

What are the physical specs and installation considerations?

This air filter is built as a square element with compact dimensions that match the intake housing used in the listed vehicles. It installs like an OEM element and requires no modification to the airbox when matched to the correct application.

• Dimensions: length 10.9 in × width 9.9 in × height 4.4 in; square shape
• Packaging: single filter per box; inspect seal and flange before installation
• Intended as a direct replacement—confirm part CA10261 against existing filter or owner manual

Who is this filter for? KAX CA10261 is aimed at Ram owners, fleet managers, and service technicians seeking a high-efficiency, long-life replacement air element that mirrors OEM fitment. It’s especially appropriate for drivers of heavy-duty Ram models and related trucks who want improved particulate protection and fewer filter changes without changing the airbox or intake system. Always verify fitment with your vehicle year, model, and engine code before purchase and follow routine inspection schedules in dusty or severe service environments.
