Bosch Spark Plugs

I prefer NGKs too, but quite frankly I've had good luck with almost everything except Champions.

Exactly the same here...it seems that 2 out of every 8 Champions will cause some grief. NGK's are a good plug and I have stuck with them for nearly 20 years now.

Nice on the two stroke and 5 years! A lot of times you can look at a two stroke and it will foul a plug ...lol

Lol tell me about it, my chainsaw is a fouling maniac, its time for new rings but I'm being lazy.
of course my YZ was getting new rings or piston every 6 mons and new cylinder once a year, but I ran her hard. Oh how I wish mopar parts were as cheap as 2 strokes lol

Bosch is overrated like a lot of German stuff. I don't change plugs often. What does an 01 anything have to do with a BB 440.

NOS HP Plugs

Any thoughts on these?

Depends on the year. Those ones are probably made by Champion. Before the middle 60's, Mopar used Autolite but switched when Ford bought that company.

Current Mopar Performance seem to be mixed, with some sources saying Federal-Mogul (who own Champion). This Summit page mentions Mopar Performance Bosch plugs. http://www.summitracing.com/int/parts/dcc-4876926/overview/

I went NGJ V Power Stock number 3332, hope they work well. Will check gap to .035, is that right before I install. Thanks for all the input.
