The Champion plugs arrived today for the FE446. I noticed when ordering and once they arrived that they are called "Racing" spark plugs? Does this mean I'll be replaing them every 300 miles or something? On a good note, they do appear to be physically correct in size, thread pitch etc.
And no, I have not installed them yet. Work, eat, sleep until Wednesday.
Actually Greg they should be built better and a little bit hotter plug..that should help some with your sooty plug situation!! and of course that broken plug didnt help matter's any? LOL...
Good Luck Bro on your next trip to the Dyno!! I Cant wait!!
So, would you say based on how my other plugs looked, that 350 rwhp wasn't all that bad? I have not looked at a lot of plugs in my time. I guess I should learn how to read them. The broken plug probably explains it running like crap on start-up.

I have never seen a true racing plug with a higher heat range than the lowest standard heat range plug for that engine series.
Well, for the extra $1 or 2 per plug, I'll take Keith Craft's recommendation. It was on his FAQ page, so it's not like his getting the extra cash. I did have to go to Jegs to find them.

Well Just going by memory? from my Altered Days...I think you'll find the heat range of race plugs to be wider than standard Automotive plugs..
I used to have a plug rack in my trailer with 4 or 5 sets of plugs in different ranges..Depending on the altitude,Air density, Temp, and track conditions..
I don't do drag racing so my opion won't mean much, but running at high rpm for any great lenghts I would use colder plugs, usually Autolite BTF6, the same plug they used in trucks that ran hiway speeds all day, but I can't find them anymore
The only thing with drag racing is there is no real extended run time. 11 seconds is not too long(for me). Yes, you can burn stuff up if the tune up is that bad off, but it's definitely not like nascar.
I guess if you are "class" racing and looking for the 'nth' of a second advantage then changing plugs for weather will do something. Us bracket racers don't screw with anything(at least I don't). Get it in the ballpark and run'r! Consistency(thru the race) is the game, not be the fastest everytime.
