Best spark plug for the k5 blazer
 

i have an 82k5 blazer, i know in 2nd gen s10s you want to stick with ac/delco premiums, what about in a 350, should i go with ac/delcos too or will a different brand work better,
thanks

For your engine, I don't think you could go wrong with the AC/Delco Rapidfires.

alright anyone know the gap size, mine didn't come with a manual:icon_playing:

For the Rapdifire (AC/Delco part #10) the gap is .035
For the standard plug (AC/Delco part #R44T) the gap is .045

i am a firm believer an the ac delco plugs.

When do you think a good time to get a manual would be?? Or maybe learn the finer points of searching...?

Just an FYI, Autozone.com has this type of information available for free.

Considering that you really have no clue what motor is in your truck other than it isn't the original motor... You might want to do some homework there. Show some initiative in finding the information yourself and maybe you will get better responses.

Huh? :icon_shrug:

In general Rich. Speaking of his past posting habits and complaints about people not helping him.

Ahhh. :icon_playing:

when have i ever complained about someone not helping me kyle????

i just got the truck a week ago, i go to school full time, work part time, get home, work some more, then if i have time between school work and work, work, i have time for the truck. try saving for college and working on a truck at the same time:icon_shrug:. its not easy. i searched for k5 sparkplugs and all i found were for 2nd gen trucks. so i figured i would ask. the truck HAD A 6.2L DIESEL, it now has a 350 gas. i always search first before i ask a question. i'd rather know something instead of guessing.:icon_doh:
