spark plug help please
What is the proper spark plug to use for my 82 K5 Blazer? I have AC Delco R43TS plugs in there right now. It has an aftermarket built 350 in it if that matters.
Thanks, RIZ |

AC DELCO plugs will be fine. I have accel shorty's because of my headers and they're fine. Champion, bosch, all are fine. Unless it's wickedly built i'd stick with AC's.

The ACDelco r43ts is what I have i n my stock engine and the 355 I'm getting ready to install. They should work fine. Another good option would be a NGK in the same heat range as the ac delcos. I run NGK in my ls2.

Re: spark plug help please
These should be gapped to .045" right? Do they come gapped straight from the box? It's been forever since I changed plugs in anything.

Re: spark plug help please
they should already be gapped but never hurts to double check.
