What spark plug

[I AM B17]

If the Autolite 2413 is no longer available...what other brand is the " EXACT " cross per heat range ???

I now use NGK, BR10EIX, or B10EGP, 2414 might still be available and is direct cross with a AG203. I know a guy that runs that plug in his Sudam on alky.

Btw, I have an old cross reference plug chart , that lists a 203 same as a 2414. As for them new,(old) , multi ground electrode, if they don't use it in NHRA top fuel, it ain't worth my time. I saw ads for them back in the 50's, just another gimmick.

Jack, What spark plug do the Top Fuel and Funny Cars run now and the Nostalgia Funny Cars??? What did they replace ther 2013 with?

 

[jack burroughs]

I have no idea, but we used either a Champ, N-54-R or a AG 403.

No Al not Nitro but Toluene (aka - Toluol)

no response on this! I asked how you knew this, but no response. I must assume then that you don't know.
