Spark Plugs

(1/3) > >>

Thunder Kiss:
My car (early '86 with iron heads) is due for a new set of plugs.
There seems to be too much choice these days - platinum, iridium, multiple-electrodes, V-shaped electrodes, etc.

What does everyone use?  Any recommendations?

TIPPA:
I've tried pretty much all the plugs you've mentioned, thunder kiss. the platinum and iridium plugs are more for longer life. instead of having a 15,000km life theirs is more like 100,000kms. But you pay for it! As for the 'V' GROOVE and split electrode types, i've paid the small amount extra but have never noticed a power increase at all. and if there was, i certainly never felt it!
I just stick with my good old favourites NGK-R.

Vette Obsessed:
I've never been big on platinum or iridium for the reasons TIPPA mentioned.

As for multiple electrodes and the like, from what I understand the spark will only "use" one of the electrodes when igniting anyway (I stand open to correction on this). I don't use them either.

I just use plain old "Champion Gold" plugs in my car - although everyone I have spoken to tells me NGK is better.

Yep!  I use Iridium's but I got 'em cheap.  ;-)  I have never liked Champion plugs - they never seem to last as well.

Stick with NGK and you'll be pleased.

86er:
I don't like Champion plugs as they are a two piece pressed plug, problem being if the thread siezes up when you remove them you leave the threaded part still in the head which means removal of the head.
NGK are about the best for the price, the other plugs are good however unless your motor is highly modified you won't notice the difference
