Quad4 sparkplugs

[Guest]

Tell me why I can't find anything when I search?

If there in fact has not been very many threads on this subject please enlighten me as to what type of sparkplug is best for the HO Quads.  I seem to remember that at bottom of the line NGK was highly recommended.

[Guest]

I know NGK are good for DSMs but for the HO quads I hear that the stock AC delco ones work the best.

AC Delco...  That's what I used in my Calais and they worked better than the 4 different plugs in it when I got it..  heh..

[Guest]

Ahhh right, the NGKs I used for my Stealth.  

Ok, cool.  So stay stock you say.

Use AC Delco FR3LS for stock engine.  FR2LS or FR1LS for modified engines.  I have Bosch in mine I think.

[Guest]

I have always used AC Delco plugs in my quad..

[Guest]

Ok, great, thanks guys.

I've got Bosch Platinums in my 90 GTZ...I would recommend them

Bought the Delcos today.  12 bucks a pair Canadian.  Twice as expensive as any other delco plug.  Will find out how they work tommorow.  Do they come properly gapped?

Those are rapidfires.. You should have just got the standard ones........................ I'd exchange em. Or you could try your luck.

I just got a set of plugs for my quad for 5 bucks. AC delcos.  I had the Bosch Platinum +4's, but the electrodes burnt off them within 20k miles or so.

[rweatherford]

Rapidfires will also burn up.  We don't know why, but we don't recommend them anymore.  I'd get my money back and get normal plugs.

[Guest]

Thats the only model they had listed for the 2.3

Can someone quickly tell me what is the proper gap for the HO?
