Spark plug range

[Scott21]

Which plug do most people run? I am getting listings from 2245 - 2242.

This has been covered many, many, many times. If you have a healthy engine then:
M38 gets the 2243
M38A1/M170 gets the 2245

The heat range availability for this application is not very good. 2242, 2243, 2245 and that's it. You can see if you have a plug fouling issue on a tired M38A1 engine you have no hotter plug to choose. But the M38 with the same problem can move up in the heat range to the 2245.

Sorry, but these are your only choices in the shielded plug and harness equipment in 14MM.
