What brand spark plug for a basic h/c/i car?

[Zombietime]

I need something to do this weekend and it's time for a plug change. I'm not sure what plug is recommended though.

Ive been using Ford tune up parts (plugs, wires ect). Am I wasting my money? The wires are shot and they have about 10k on them. Is there a better product?

 

[Scorcher2005]

MSD has some nice wires. Infact - im bout to order some super conductor wires and autolite 25s.

Autolite 24 or 25. 25 probably a little better.

i use autolite cooper core 764 plugs. they any good?

 

[dromeda]

Autolite 25s (24s if you're blown, I think don't quote me on that)

 

[stangbear427]

Autolite stock replacements, or Motorcrafts. On any NA stang. Anyone who tells you differently is either just trying to sell you something, or make themselves feel better about what they bought.

Autolite 3924 for N/A and 3923-3922 for blower applications and longer threads for aftermarkets heads..The Autolite 24's are for stock heads
