Mopar 2019–2024 Ram 6.7L Cummins Genuine Dual Fuel Filter Bundle (68157291AA & 68436631AA) | OEM Set
Description
The ultimate 15,000-mile fuel-system insurance. The 2019+ Ram 6.7L Cummins runs an incredibly powerful high-pressure common rail system that is highly sensitive to fuel quality. The Genuine Mopar Dual Fuel Filter Kit includes both the engine-mounted NanoNet® filter and the frame-mounted water separator. Don't risk a crank-no-start condition or a $10,000 injector repair with cheap aftermarket filters — run the factory-spec protection that built the Cummins reputation.
Technical Significance
Modern diesel filtration is about stopping microscopic silt and emulsified water, not just dirt. This kit pairs the 68157291AA NanoNet® filter — the industry's best polishing filter — with the 68436631AA water separator. Together they deliver 98.7% efficiency at 4 microns: the only way to keep your CP4.2 high-pressure pump lubricated by clean, water-free fuel and prevent the internal scoring that leads to catastrophic failure.

| Water Separation | Optimized for CP4.2 high-flow pump | Inconsistent under high pressure |

★★★★★ Best insurance policy on a $70k truck
My 2022 Ram 3500 Laramie is my livelihood — I haul equipment every day. Running genuine Mopar OEM filters is just not negotiable for me. Both filters in this bundle are genuine, came in factory sealed boxes, and installed without any issues. Water-in-fuel light has never come on, fuel pressure is always spot on. Do not cheap out on this service.
