View product →Engine & part-number match
Set of eight AC Delco 41-983 spark plugs listed with PCM RP030009 as a comparison reference. Match the current plug number and exact engine/ignition specification before ordering; confirm the correct gap from the service information for that engine.
Before ordering
- Engine model and serial number; the boat year alone is insufficient.
- Complete number on the existing part and any replacement/supersession reference.
- Printed plug identity, terminal type and required quantity.
Exact replacement needs confirmation. Use the checks above so GT40 can confirm the correct part.
