2025-2026 Ram 6.7L Cummins Oil Filter — Direct OEM Replacement for 68677810AA
Engineered for 2025-2026 Ram 2500, 3500, 4500, and 5500 trucks equipped with the 6.7L Cummins Turbo Diesel engine, the iFJF Oil Filter delivers RF32410LPNP phenolic resin filtration that directly replaces OEM part numbers 68677810AA and LF16453. Whether you're daily commuting, heavy hauling, or fifth-wheel towing, this filter keeps your engine oil clean and protected against metal debris, carbon deposits, and microscopic contaminants.
Built for Your Cummins — Real-World Usage Scenarios
🛣️ Daily Commute Protection
Heavy-duty trucks driven daily on city roads and highways face gradual accumulation of metal debris, carbon deposits, and combustion byproducts in engine oil. The iFJF oil filter with RF32410LPNP phenolic resin impregnated filter media continuously captures 20μm-level particles, providing foundational engine lubrication protection for everyday driving.
🚛 Heavy Hauling & Towing
When your Ram is under sustained high load — hauling equipment, towing fifth-wheel trailers, or carrying heavy payloads — engine oil temperature rises and viscosity demands increase. The iFJF filter's 483kPa cured burst strength (ISO 4548-12) maintains structural integrity under continuous high-temperature, high-pressure conditions, ensuring consistent oil flow and filtration performance when your engine needs it most.
🏗️ Harsh Environment Operation
Dust, vibration, and extreme temperatures in construction sites, farms, or off-road environments challenge oil filter durability. The RF32410LPNP media undergoes 170°C high-temperature curing, and the reinforced sealing design maintains leak-free performance and filtration consistency under severe operating conditions.
❄️ Cold Weather Starting
In winter, engine oil thickens and filtration resistance increases significantly during cold starts. The iFJF's anti-drain back valve and high-flow media design ensure oil reaches critical engine components quickly, reducing cold-start wear and protecting your Cummins from the moment you turn the key.
🔧 Fleet & Regular Maintenance
Replacing oil filters at manufacturer-recommended intervals is the most cost-effective way to extend engine life. The iFJF's ready-to-install design with pre-lubricated gasket lets both DIY owners and professional mechanics complete oil changes efficiently — no special tools beyond a standard oil filter wrench required.

Frequently Asked Questions
Q: How does this filter compare to the Mopar 68677810AA from the dealer?
A: Our filter uses RF32410LPNP phenolic resin impregnated media from Shandong Renfeng (SD) — the same material grade used by OE filter manufacturers. Key tested values include 483kPa cured burst strength (51% above the >320kPa minimum) and ISO 4548-12 certified filtration efficiency. The performance is equivalent — the main difference is you skip the dealership markup.
Q: How often should I replace this oil filter?
A: We recommend replacement with every oil change at 15,000 miles (24,000 km) or once per year — whichever comes first. If you frequently tow heavy loads (>10,000 lbs), operate in dusty conditions, or idle extensively, consider shorter intervals of 7,500–10,000 miles. Always follow your vehicle's owner manual recommendations.
Q: Will this fit my 2025 or 2026 Ram 2500 with the 6.7L Cummins?
A: Yes. This oil filter is a direct OEM replacement for part number 68677810AA on all 2025-2026 Ram 2500, 3500, 4500, and 5500 models equipped with the 6.7L Cummins Turbo Diesel. It also replaces Fleetguard LF16453. Please verify your existing part number against the Compatibility table above. If unsure, contact us with your VIN and we'll confirm fitment within 24 hours.
Q: What happens if I don't change my oil filter regularly?
A: A clogged or bypassed oil filter can lead to:
- Unfiltered oil circulating through the engine, carrying abrasive metal particles that score cylinder walls and bearings
- Reduced oil flow causing inadequate lubrication of turbocharger bearings — a leading cause of turbo failure in Cummins engines
- Accelerated timing chain and valvetrain wear from contaminated oil
Regular oil and filter changes are the most cost-effective maintenance you can perform on a diesel engine.
Q: Is installation difficult? Do I need special tools?
A: Most DIY owners complete the oil and filter change in 30–45 minutes with basic hand tools. You'll need:
- A standard oil filter wrench to remove the old filter
- A drain pan (12+ quart capacity for the 6.7L Cummins)
- The new iFJF filter — pre-lubricated gasket means ready to install out of the box
Hand-tighten until the gasket contacts the mounting surface, then ¾ to 1 full turn. Do not over-torque.
Q: Does this filter work with synthetic oil?
A: Yes. The RF32410LPNP phenolic resin media and oil-resistant gasket materials are fully compatible with both conventional and full synthetic diesel engine oils, including 5W-40 and 15W-40 grades commonly used in the 6.7L Cummins.
Q: What do the ISO certifications on the filter paper actually mean?
A: Here's what each standard validates for the RF32410LPNP media:
- ISO 536 — Basis weight: 211 g/m² (heavier media = more filtration material per square meter)
- ISO 534 — Thickness: 0.85 mm (consistent thickness ensures uniform oil flow and pressure drop)
- EN ISO 7231 — Air permeability: 465 L/m²·s (controlled porosity for optimal oil flow rate)
- ISO 2942 — Max pore size: 88.7 μm (verified pore structure for contaminant capture)
- ISO 2758 — Cured burst strength: 483 kPa (won't rupture under pressure spikes)
- ISO 4548-12 — Filtration efficiency: 51% @ 20μm, dust capacity: 185 g/m² (real-world filtration performance)
These are the same testing standards used by OE filter manufacturers to validate their media — not generic marketing claims.
