The MPI Automotive MKNI0084 is a DPF-and-cat replacement listed to fit the 2.5L automatic Nissan Pathfinder R51 (Thai-built). It renews the factory diesel particulate filter and catalyst section rather than adding flow or volume.

What's a DPF replacement and where does it sit?

The diesel particulate filter traps soot in the exhaust and is a known wear item on diesel SUVs of this era. The MKNI0084 replaces that filter-and-catalyst section on the 2.5L R51 Pathfinder, so it's a renewal part rather than an aftermarket upgrade. It puts the soot-handling and catalyst hardware back into serviceable condition. Because it renews the catalyst-and-filter section in place rather than removing it, it's a maintenance part rather than a louder aftermarket upgrade.

Why does the Thai build matter?

The R51 came out of more than one assembly plant, and this listing is matched to the Thai-built 2.5L automatic specifically. The Spanish-built equivalent carries a different part number, so the country of build is what keeps you on the correct replacement section.

Will it suit my Pathfinder?

It's listed to fit the 2.5L automatic R51 Pathfinder, Thai build. Because build origin and engine spec decide the fit here, send us your exact details and we'll confirm before ordering. Get the build wrong and the section may not line up at the connections, which is why we check it against your vehicle first.
