nycredneck 12 #1 Posted April 14, 2020 1988 518H, E1-18OE01, aka... 31-18OE01. I would like to install correct plugs after installing new coil and ignition module. I will be putting new wires on as well once I know the correct plugs for that Onan engine, thank you. Share this post Link to post Share on other sites
