R=resistive (basically all plugs these days)
42=very COLD plug, I'd say it must be a pretty high compression engine its going in

L=don't know off the top of my head what that means.......

T=Tapered seat, usually all plugs in the 70s and up use this

S=extended tip, allows a larger gap (.060 is possible) usually used on HEI and DIS cars (As opposed to older points style ignition)

For example, my 67 impalas 327 calls for R43. Not tapered seat, and not extended tip because it came with points from the factory and ran 0.035 gap. Fairly high compression stock compared to late 70s early 80s cars.


I"d have to look up the L to make sure but the cold plug is really strange because most late 70s to mid 80s used hotter plugs due to shitty compression ratios. I'd have to say that it must be something in the 90s......need to see what the L means.

BTW, a cross reference really wont tell you much. An R45TS fits in everything from 70s chevy to 80s mustang 5.0s...same plug.
