Not a one (Autozone, Advanced, CarQuest, O'Reilly) had Champion spark plugs for a '67 MGB today! Neither did they have oil filter or in-line fuel filter!

Seems they're no longer carrying Champion 9's but have switched to 12's because that's what fits newer cars! Glad I had several sets on the shelf.
 
Interesting....I have a lifetime supply of N9YC's but usually have trouble finding enough N12YC's. (Jag 6/12's)

Well, I know where to get you all the RN12YC's you need!
 
Hey Tony, is there any reason not to use a "R" series plug (resistor) over a non, as in RN12YC vs N12YC?
 
As I understand it, the "R" just gives you a resistor for radio, etc. I'm using RN9YC's on my '67 GT that's getting a tune-up today...I think its getting harder to find plugs without the resistor unless you order from someplace like Moss - I don't need the resistor because my '67 doesn't have a radio, but I don't see how it can hurt.

I'm more concerned with the copper! But I want to see what happens.
 
If you're using "suppression core wires" (i.e. non-solid core) you should be fine with either plug type.

If you have solid copper core wires (ie. Lucas bumblebee) you'll want R plugs.

Good to know, Scott - I'm putting Bumblebees on the car today!
