for an 87 that will run 13 to 14 second times in the 1/4 what is really the best sparkplug to get.
western new york state avg outside temp when running is 65degrees at 1700ft elevation.

The AC Delco R43TS with a Tight 035. gap have worked fine for my stockers. Also the AutoLite
24 was fine too.

i thought you guys might say both so i guess i will flip a coin now to see which ones will go in .anybody got a canadian quarter there not using.lol

The CR43s are great too. Makes no difference, buy which ever ones your store carries

 

[Steve Wood]

and if your store does not have one of those three.....then go for the NGK UR-5s

No platinums, no ac rapid fires, no splitfires, no champions

I like the CR43TS best. I noticed with the NGK's I got radio interference but performance was same as the AC's. dunno
