The reviewer found the combo saves time hunting parts and delivers filters that match expected fit and performance, keeping a diesel truck running cleanly when swapped on schedule.

Key Features

• Complete kit: Includes a fuel/water separator, fuel filter, oil filter and engine air filter so a full service can be completed without multiple orders.
• Direct fit: Compatible with Ram 6.7L Cummins 2500, 3500, 4500, 5500 for model years 2013-2018, reducing compatibility guesswork.
• Interchangeable parts: Each filter is listed to replace common OE and aftermarket references, simplifying cross-referencing during maintenance.
• Tested filtration: The fuel/water separator and oil filter carry independent micron efficiency ratings to help protect injectors and engine oil systems.
• Dust capacity: The engine air filter is tested for dust holding capacity and high efficiency, offering reliable engine protection in typical driving conditions.

Who It's For

This kit is aimed at Ram owners with the 6.7L Cummins engine from 2013 to 2018 who prefer to do scheduled maintenance themselves or who manage multiple trucks and want a bundled parts solution. It suits DIY mechanics who appreciate clear interchange listings and independent filtration test results.

Those who should look elsewhere include owners needing filters for other engines or model years, or anyone who requires OEM-branded boxes for warranty-specific service recordkeeping. Also, shops that stock a specific single-brand filter line for warranty reasons may prefer ordering components individually.
