just curious, what part# are the AC Delcos that you put in?

When i search for AC delco plugs to my 1997 Blazer 4.3 Vortec, 41-913 platinum plugs are recommended. Could i still use CR43TS to save a little money?

If i search for plugs for the same car but 1995 model CR43TS are recommended. Is there something changed in the engine configuration between 95 & 97?

Thanks,

/qsec

open your hood, look at the emission sticker, and use what it says on the emission sticker....

Thanks, but on my sticker it just says the gap should be 0.60.
