Since the Bosch plugs everyone touted as being so great have been discontinued, which 14mm spark plug is the 'hot ticket' now to use on a 'Z' headed engine with stock-type plug wires?

TIA!!

Brent,

Good thread, and i will watch every answer.....
I have never been able to get a 14 mm plug to work well in a model t . I have three cas and drive them more than most and just cant ever get a 14mm to work.....

I never tried the 14mm plugs but I tried all the others and have found the good old Champion X to be the best but just barely edging out the Autolite plugs.

I use Bosch #4003 for several years with good luck in each of my 3 T's and set them @ .065 with electronic ignition or .030 without.

Roy, are they still available?

Brent, I just checked online & they are. You might try your local auto parts store. They changed from #4203 to #4003 a year or so ago. I bought a set (spare) a few months ago.
