Spark plug Question...better spark?
I get a monthly auto parts flyer with some good coopin's I always see spark plugs on sale with platinum (good), double platinum (better) and iridium (best).
Is there a good, better, best/iridium plug option for the Flathead that would work, or just stick with the Ol' champions. I hope this does not turn into a (best oil) thread. Thinking Bubba/Walt ect. may have some good input, thanks. Scott |

I'd have to see proof what makes these expensive plugs so much advantage over a set of 216 Autlite in you 39 pickup. Walt

Not that I know a lot, but.....
Aren't the high end jobs built for hyper-extended use and copper used for making bigger spark? I would think that we all want the advantage of the bigger spark. Besides - be honest....can you really keep your hands off of them for 100,000 miles?

Re: Spark plug Question...better spark?
The reality of it all is marketing pays off..
The spark plugs job is to ignite the air fuel mixture in the combustion chamber. Assuming everything is factory ie: carb, camshaft compression etc there is nothing on the planet better than a factory rated spark plug per engine application. And then the discussion starts!! Plug construction may be changed or modified to fix a particular problem. Newer plugs have a coating to help them not stick in the engine , heat range may be changed to work better with a engine change , tip construction may be adjusted to better meet the flame front. However all changes are in place for a particular problem... One example ( out of many) would be the addition of a five speed trans mission. The 5 speed lowers the cruise rpm of the engine ( in some case one half) and a different heat range plug may be needed for the slower speed of the engine . ( more than likely one range hotter ) If we think the oil discussion is long then the plug discussion is every bit as long. |
