spark plugs

[KClarke]

Have any of you noticed that the 3.4 V6 asks for a dual ground plug in it? What about the Bosch 4 plug, is it as good as they claim and are they good in the 3.4?

All it is, are more grounding points for the electrode. In my opinion, if you stick with the OE it's already pre gapped and you can't go wrong.


Just my 0.02 cents

BOSCH plugs are horrible.

NGK or DENSO is what 90% of Japanese manf. use in their cars.

STICK with OEM.

Agree..
I installed NGK Iridium (single electrode) a couple of months ago and its running nice and smooth.

No need for any special or fancy platinum, iridium, etc. in the 3.4L engine. The best is a twin prong plug (even specifies that a single prong should NOT be used in the manual). Get OEM. They're cheap. Don't waste money on other plugs that won't do anything but lighten your wallet.
