What NGK rep post was that? I'd like a link to the thread if you have it. I'd like to read it.
The info
I got in an email from an NGK tech warned against using projected tip plugs in a kdx. He said he saw plenty of gripes every week from riders thinking that NGK ought to pay for the engine damage caused when a projected tip plug broke inside their engines.
milhend: I don't know if you already looked at this regarding projected tip plugs (you had asked about them a couple months ago..):

Given that (notwithstanding further input that jasle can post from NGK) NGK warns against 'P' use, so I wouldn't use one. Still, I found the 'G' fine wire nickel to be a considerable improvement over the 'ES'. The
finer wire V, VX plugs would be fine (groan), too...if you don't mind spending the $. The 'G' seems a good middle of the road plug..performs better than an 'ES', and doesn't cost TOO much.
BTW:
1. NGK's VX is noted to be a
platinum center electrode.
2. NGK's EV is noted to be a
gold palladium construction.
3. They list the 'IX' as an
iridium plug
...but they don't have a
titanium plug. ;)
And the above come in a variety of 'fine' and 'ultra small' center electrodes....and 'fine' doesn't always mean the same thing!
Obviously they want to keep it all real simple!!
