set gap on plugs

Featured Replies

I used feeler gauge to verify the gap on new platinum plugs for my 05 OB and then I read that this could damage the plugs??

Any idea what they are referring to? Is the platinum that delicate that I might have damaged it??

Apparently,platinums can be that delicate.

 

News to me too.

Just spoke to a dealer who said they do verify the gap. "Ya never know if someone previously bumped the plug..."

Any other comments from the cheap seats?

Seeing as 99% of Platinum plugs come pre-gapped, there is no reason to stick the gap meter to them and you will damage the electrode by doing that.

Well, two dealers warned about on-line mis-information but said that while NGKs are usually spot on and they can usually eyeball them, they can check them if it doesn't seem right without damage.

I think as long as you don`t force a tight gauge you are OK.

I use the Bosch Platinum, single electrode model. They never need to be gaped before installation. With such a hot spark going to plugs these days, I don't think that gaping is that important anymore. Seems like anything that I have bought already has a decent gap as set at the factory.

 

Plugs that I pulled out of my OBW with 148K miles were very widely gaped from wear, and had to be way out of gap spec, but still performed well enough.
