Spark plugs cross reference Excalibur

[jos]

Hi there,

Does anybody now the spark plugs cross reference of the 5.8 Excalibur 330. 2003-SAN210

Running excellent on pump gas, perfect is the word.
Runs also on propane, but not as smooth, want to exclude plug mis fire-ing on propane by trying some standard plugs, not the platinum. Troubleshooting likes to exclude step by step.
Propane specialist says start at the plugs, propane is ignition sensitive, burns slow. Plugs do not wear on propane but can bring some hard and misty diagnose.

Glass Water to you all.
Thanks for your help
Jos

Hi Jos.
The correct standard plugs for the 5.7 Excalibur 330 are AC Delco model AC MR 43 LTS.
Good Luck!
