put an AC next to a Champion and you'll see.... NGK's are a decent plug too.....
 
Bosch platinum plugs...UGHHHH....

I had a lot of Bosch Platinum plugs give me grief--some refused to fire right out of the box!--others died a week or two later...more than one vehicle I put them in had a dead cylinder after the tune up,and I had to put an old plug back in!...I wont use them in anything I own...they only seem to work in the newer vehicles that came factory with them...AC Delco or Autolite plugs are best in chevy motors in my experience--champions dont always work good either....I dont care for them at all...Only reason I put the Bosch Platinum plugs in was the customer bought them at autozone cheap--I'd never waste my cash on them... :crazy:

AC delco plugs last longer and work better over the life of the plug than any other plug that I have ever used in a V8. Including those POS Bosch platinium plugs.
Any plug that costs more than AC delco is just a waste of money IMHO
Plus I like the fact that both my Blazer and my Mustang use the exact same AC delco plug.CR43TS
 
sorry not trying to make anyone mad, just wanted to know why everone likes to use them. Next time I do a tune up Ill get some.
 
I've always had great luck with the AC Delco Rapid Fires. I know Checker doesn't carry them anymore, but I think Auto Zone does.
 
Delcos work the best because they are the plugs that the factory tested and built for. Auto lites work really well also. Champions aren't worth the powder to blow them to hell in a Chevy; Dodge is the only company that they run well in. As far as platinum plugs go, don't waste your money. Everyone seems to think that they offer a performance upgrade, but all they offer are longevity. The Bosh platinum 2 and 4 are the exception, but only run well in DOHC engines. Standard platinum plugs are no good in older V8 engines as they have a tendency to have the platinum tips blown off under high compression, which increases your gap and makes them run horrible. Being a manager at Auto Zone I get to see what works well and sells well. I run Auto Lites in the 454 I put in my 79 K5.
 
Wahh12. Totally agree with ya about Bosch platiniums in V8s. I have used them in a HC engine and the tips burned back and the insulator cracked. I know they work good in some engines. But I will never use them again in a V8.
Autolites are my second choice in plugs. Good plug but dont last as long as Delcos. I usually get around 30K miles out of a set of AC delcos. Just replaced a set in my k5 that have been in for about 3 years and still sparkin good.
 
DENSO Iridiums......
Spendy spendy spendy... Put them in my stroker motor and noticed big over the autolites that were in there.
In my trail rig I have the AC Rapid fires these are also spendy.. Good luck.
 
Sparkplugs

All those "Plus 4" and platinum whatnots do is make a weak ignition system seem like it's performing better because they're easier to fire and it provides a weaker spark, but a spark all the same where there may not have been one before. AC Delco's always seem to work pretty good for me.
