RARAYC 6.7L Cummins Filter Kit for Dodge Ram 2013–2018 — 5‑Piece Fuel/Water‑Separator, Oil, Air & Cabin

This RARAYC kit bundles the essential filters needed for maintenance of 6.7L Cummins engines in Dodge Ram 2500, 3500, 4500 (2013–2018) and Ram 5500 (2015–2018). Each component is engineered to trap contaminants, separate water from diesel, and protect engine components and HVAC systems. The set matches common OEM part numbers so it fits directly or functions as a reliable aftermarket alternative for routine service.

How does this kit improve fuel system reliability?

The kit includes a high-efficiency fuel element and a dedicated fuel/water separator designed to remove water and particulates before they reach injectors. Cleaner, drier fuel reduces clogging risk and helps maintain consistent injection performance under diesel conditions.

• Fuel filter media captures fine particles down to 4–5 microns.
• Double-layer micro paper separates water from fuel for safer combustion.
• Fuel/water separator removes up to 99% of free water contaminants.
• Compatible replacements for Mopar and common aftermarket part numbers.

What exactly is included and which OEM numbers does it replace?

The package supplies five replacement elements so you can perform a full service in one visit. Each piece is intended to match or replace specific Mopar and popular aftermarket references for straightforward installation.

• Fuel filter: replacement for Mopar 68157291AA, Wix 33255, Purolator F36294.
• Fuel/water separator: replaces Mopar 68197867AA, Wix WF10112.
• Oil filter: compatible with Mopar 05083285AA, Purolator L45335, Wix 51607.
• Engine air filter and cabin air filter: match Mopar 53034051AB and 68406048AA respectively.

How does material quality affect filtration performance?

RARAYC uses a multi-layer filter medium to balance airflow and contaminant capture. The construction reduces flow restriction while maintaining high particle retention, resulting in efficient filtration without starving the engine of air or fuel.

• Double-layer micro filter paper for staged filtration and water separation.
• High-grade media removes 99.9% of particles 5 microns or larger.
• Designed to sustain diesel flow rates demanded by turbocharged engines.
• Durable filter frames to resist collapse under pressure differentials.

How simple is replacement and what maintenance schedule should I follow?

Physical fitment mirrors OEM dimensions for plug-and-play swaps in most routine service procedures. Follow manufacturer service intervals or earlier if operating in dusty, wet, or high-load environments to protect injectors and airflow systems.

• Replace fuel and water-separator at manufacturer-recommended intervals or when water contamination is detected.
• Change oil filter at every oil service; use correct oil type and capacity.
• Swap engine air and cabin filters annually or sooner in dusty conditions.
• Inspect seals and O-rings during installation to prevent leaks.

Who is this for: This all-in-one RARAYC filter kit is aimed at owners and technicians who service 6.7L Cummins-powered Dodge Ram trucks from model years listed, and who want a single-purchase solution that covers fuel cleanliness, oil protection, intake air quality, and cabin air comfort. It suits fleet managers, independent mechanics, and hands-on owners seeking OEM-equivalent replacements without buying individual parts across multiple suppliers.
