MPI Automotive Nissan Pathfinder R51 2.5L Auto THAI DPF & Cat Replacement.
Category: Complete exhaust systems


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.
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.
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.
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.

We source these through MPI Automotive, and where the Thai-build section isn't on the shelf we can order it in once your build is confirmed.
