Just curious to hear what everyone thinks. I've heard that a plug won't properly charge after the first foul and I've also heard that you can clean the things indefinately. I usually switch mine baseball style-after 3 fouls, they're out What's your rule?
An engine that fouls plugs gets the cheapest again and again. I hate when they get wet and you have to roast them back to life. They're worn out when the spark surface is burned or the insulator looks pre crumbly.
Oil fouled plugs can be cleaned a few times ,But Gas fouled plugs seem to be DOA-in my opin ion.......
When they say Champion. Gas fouling seems to be the death knell. After that they seem to foul very quickly for me. After the second cleaning I swap 'em out. Fairly cheap insurance and the old ones are fun to throw at squirells.
I know of people that ride bikes and keep cheap old plugs on hand. When some ***hole in an SUV nearly runs them off the road, they cut in front and toss one of those ****ers down.Porcelain vs. safety gl***=broken windshield. A little extreme, but I wish I had one when I was run over
Can't agree more... They may have been good sparkplugs in the past (or maybe there wasn't anything better perhaps) but I won't put ANY of those things in my engines anymore. When I got into cars my first couple of sets where Champions, but had nothing but fouling and trouble with them. Even tried different heatranges, but to no avail. I do have got the best experiences with the Accel plugs though. Those yellow ****ers seem to last years in my cars.
So is Accel whaat all the kids are using nowadays? I just put bosch in my truck. Any advice on good plug manufacturerererererers?
My daily driver is running super rich (if you placed a torch under the exhaust tips you can create flames). I’ve taken the plugs out a couple times after it starts to sputter and misfire. I clean them up with a torch and put them back in. After they look beyond repair I throw them out. I should probably look into why my car is running so rich one of these days…
Up until the mid '30's, plugs were made as 'take aparts' that could be dis***embled and cleaned up, then put back to gether and run another six months or so (see pic of Champion C-4's for a '32 Ford below). Fouling didn't really have any effect back then on plugs of course they were only guaranteed for 10,000 miles due to the ignition systems of the day.
I've never actually been able to kill a plug from fouling. Standard gas and oil fouls get the torch to clean/dry them. If I have access to one, I sandblast'em.
