I swtiched to these plugs about two years ago when I went FI with CTSC. I have had a good handful of instances with electrical failure. I have read here that the 7173's possibly cause interference 
I have the thought of switching to a different plug, but haven't done so yet.

Why would any of you that use NGK7173 -- a non-resistor plug -- choose this plug over an equivalent resistor version?
The stock plug is a resistor plug.
I know, I know, you say "I haven't had any problems", but why would you choose to run a non-resistor plug when Honda, NGK, AEM and just about anyone that tunes for a living says not to do it?
Not looking to pick a fight, just want to hear a logical reason for doing this other than "everyone else does it" and "I haven't had any problems".
By the way, the NGK BKR7E is the same copper v-groove plug, but it's a resistor plug -- and costs exactly the same.

I switched from the 7173 to the BKR7Es a few years back and they work great.
