Did I forget to say? I use L87Y or L87YC set to 0.025". That's the plug
Champion recommends for the TR2/3/4. It's an extended nose plug, giving
it a fairly wide heat range compared to the original plugs. If you buy
them now you'll get L87YC rather than L87Y. The only reason I mentioned
the old L87Y is that I bought a case of them about fifteen years ago at a
local parts store's going out of business sale. Sold a bunch at flea
markets, gave them away as raffle prizes, but still have several sets
left. They're correct for TR2/3/4 _and_ T-Type MGs, which is
convenient. The set currently in the TR4 are L87YC. Don't remember why
I went out and bought them instead of using L87Ys from my stockpile. The
only difference is that the L87YC has a copper conductor.

If NGKs do the job, then by all means use them. Unless you use cheap
no-namers from J.C.Whitney or some place like thhat, the brand doesn't
really matter as long as the heat range works for your engine. I've never
had fouling problems with the Champions, unless the engine was a real oil
burner or the mixture was way too rich. The set currently in my TR4 have
been there for about 40,000 miles. The electrodes are pretty badly worn
so I'll have to replace them one of these days, but they're clean as a
whistle.
