Hello, I have looked all over and have not been able to find the NGK DCPR8EIX-9. I was wondering if anyone knew a source for these?

I know nothing of the seller.

All the other places do not discriminate between what appears to be a pre-set plug gap.

I just Googled NGK DCPR8EIX-9 and found this, they use IX instead of 9 but unless roman numerals have changed that's the same thing.

The IX indicates Iridium, the -9 indicated a larger factory gap (.9mm)

When manufacturers make a plug the electrode lengths are tailored for a particular gap so the side electrode stays square to the center.

If you open the gap to past square it promotes erosion of the center electrode.

This...


And, Iridium plugs are tough to gap anyway. The electrode is very thin and as strong as the metal is, they've been known to break when attempting to regap.

Are the side electrodes iridium also?

All the precious metal plugs I'm familiar with have a center electrode of the 'spensive stuff and a steel ground electrode.

Nope, just the center. That's what I've seen snap off, it's only 0.6mm in diameter.

If someone snaps the center electrode off gapping a plug...

they shouldn't be gapping a plug. :P

The way I've seen it done is using the gapping gauge as leverage against the center post to increase the gap.

The gapping tool shouldn't use the center electrode for leverage. Those cheap discs are notoriously inaccurate anyway.




Get a proper tool.

Agreed. Just explaining how he did it...
