Spark Plug help - conversion from Torch plug

Can anyone provide a conversion from a Torch L7T spark plug? I can find Champion, Denson, NGK and Autolite plugs for Torch L7TC but not L7T plugs. Or, does anyone have any idea whtat the "C" might mean. Plug measures out the same, same gap etc.... Just a slightly different part number.

Thanks -

Mark, Not for sure but most of the time last letter has to do with an electrode design feature that is not critical. I will check some resourses tommorrrow and get back to you.
 
I'm assuming that it is a newish motor. Look inside on the tag or in the book and see what is called for most times there are two numbers listed both the same numbers just one has a letter dropped. Most times the letter drop is a non suppressor plug. Two letters are normally Suppressor plugs, they will not allow ignition feedback to interefere w/ electronics. Non-suppressors possibly will.

What does "look inside the tag or in the book" mean?

So what you are saying is that to run a suppressor plug in place of a non suppressor plug should not be a problem?

Mark,
Typically that is correct. Suppressor or non suppressor plugs will interchange engine performance wise as far as physical dimensions, heat range, etc.
