Plug Number 63 413

["Clint and Laurie Carter" <laurielu@xxxxxxxxxxxxx>]

Just a word of caution on spark plugs. You should always look up spark plugs
using a catalog, not just interchange numbers from one brand to another. You
can go up to a hotter plug, of course if you have an oil fouling problem,
but start by looking up the correct plug in a catalog, and go hotter from
there. The interchanges are close but are meant for a reference only.  I
worked auto parts for many years, and believe me, I know from whence I
speak.

resistor plugs, so this never occurred to me.

another IML'er asked the number for the 413, but I wanted to provide a
current number, so I called my parts supplier and he gave me the "75" for
the '59-'65 413. Interestingly in Champion, there were two numbers that
would fit, one was a "high performance" plug. I gave the IML'er all of the
numbers and recommended that he check a tune up parts Web site to verify the
numbers. I haven't heard that the "75" wasn't the right one for that car.. I
suspect that possibly a "75" is the standard plug, and that the "85" may be
a hotter plug. It is also possible that the parts guy was completely wrong.

thinking that I may have bought "85"s for a '65 Chrysler 300 Coupe that I
used to have.

I have the Champion number too, RJ12YC or RJ14YC.
