Fuel and Oil Filter Kit for 6.7L Cummins Diesel - Reliable Fit

In this review of the AULDAY fuel and oil filter kit, the bottom line is straightforward: this set is for owners of 2019-2022 Ram 2500, 3500, 4500 and 5500 trucks with the 6.7L diesel who want a direct-fit, economical replacement. The reviewer found the kit delivers a proper fit and solid construction, and the included 5 micron fuel filters target debris and particulates while the oil filter matches OEM form. For routine maintenance or preparing a truck for winter or heavy towing, this kit provides a practical, value-oriented option.

Key Features

• Direct fit compatibility: Designed to match the replacement needs of 2019-2022 Ram 2500, 3500, 4500 and 5500 6.7L diesel engines, making installation straightforward for owners and technicians.
• 5 micron fuel filtration: The fuel filters are rated to 5 microns, which helps trap fine contaminants and protect high-pressure fuel systems under heavy load.
• Complete kit: Includes the fuel filter elements and the oil filter reference part for a combined service, reducing separate sourcing and downtime.
• Good value: Customers report the kit delivers quality and fit at a lower cost than some dealer parts, making it attractive for routine maintenance budgets.
• Brand consistency: Supplied by AULDAY, the kit presents a consistent set of parts intended to work together for a single service interval.

Who It's For

This kit is best for Ram 2500-5500 owners with the 6.7L diesel who perform their own maintenance or use an independent shop and want a direct-replacement filter package that balances cost and quality. It suits drivers who tow, haul, or log many highway miles and need reliable filtration to protect fuel injectors and the engine oil system.

It is less suited for owners who require dealer-branded parts for warranty reasons or those who need filters with different micron ratings or aftermarket performance claims. If you need extended-life or specialty filters, consider dedicated high-performance or OEM-branded options instead.
