either cruiser or walker said champion coppers... so last tune up, the chief got coppers, i was running ngk platinum's, it ran pretty good for 6 years on them...

 

Who uses those like diamond four pronk spark plugs how would they work

 

I have been using bosh +4 for the last 30.000km, no problems

 

Regular champion copper....they only make one spark, no matter how many prongs there are.

 

I got some autolite platinum plugs. Has anyone tryed them or should I take them back and get coppers?

 

88 4.0 NGK V-Powers

 

on stock engine, nothing but champ coppers here. Ive used a few different ones on mine, ngk, bosch and the champs coppers are best. Ive changed out several plugs on freinds rigs with the champ coppers and they say its never ran better, some said it ran worse after a shop put "fancy" plugs in.

 

 

x2, you'd have to ask NAPA for the number.

 

Champion coppers are the best for these.

 

I bought one of the Accel tune-up kits and installed the Accel plugs that came with the kit. Would I be better off installing Champions?

 

Ill probably just use NGK v powers. I haven't found a car yet that didn't do good with the reg v power NGK plugs. I have found bosh to be complete shyt, even my Porsche didn't like Bosch, never found any plat plug to be any good.
I have heard alot of people rave about iridium plugs, but I have a feeling they suck for the price. I wasnt pleased with champion in any mopar based vehicle i have installed em in yet. I have seen autolite coppers work great in 302 fords, but nothing else

 

no go take em back fo sho lol

 

i have bosh iridiums in my 530 and it ran alot better and had more power. worth $8 a plug? not really. ive had ngk's ceramic just break before and autolites are complete crap. just my opinions tho

 

In 42 years I have never had an NGK fail on me. Bosch Platinums, yes. Champion, yes.
