Genuine Part
These are Cummins parts. The difficulty with installing is not based on the plugs but the placement for them on the generator.

Made for my Model Onan Generator.
With the investment I have in my motorhome... I want to keep it regularly maintained with the best OEM products available. RV Generators are not cheap so don't scrimp on the quality of your replacement parts over a few dollars. There is the possibility of ending your warrantee by using knock-off parts. This spark plug is recommended by the Onan Generator Manufacturer so... peace of mind for me! Plug was gapped correctly right out of the box.
