Default Re: Spark plug preference...Curious

Use raja ends, so autolite plugs removable ends, works for me 216 or 218 18mm, I can look up the plug to be certain... (in 14mm it's like 486 for autolite). NKG doesn't make them that I know of with screw tops.

Could go with a hotter plug then the champion h10. The new plugs have good reviews. But let us know!!!
