I use to run copper plugs . I would always have erratic modifry temp gauge readings . I put in some good ngk iridium plugs and my temp gauge works perfect now . Oh and this is with Aem 1052 ems . Spend the money and do it right !!

Your problem had nothing to do with them being copper plugs, it had to do with them being non resister copper plugs.

Who sells the BKR8E-11's? None of the chains seem to carry them (Napa, Oriley's, Autozone, Advance) and the one Amazon listing for them seems sketch.
I haven't experienced any issues with my non-resistor R5671A-8's, but if you guys think its better to run resistor plugs I guess I'll switch

It is tough to find. I don't think the plug has any OEM automotive applications, which is why auto parts stores don't have it. There is actually an OEM Honda Motorcycle part number for the plug.

You may have luck finding it at you Honda bike shop. The OE application is a XR650R. I know its also used for boat motors. If you want to run NGK copper plug, with a resister at heat range 8, its the only option. It is the exact same as the BKR7E that everyone runs but it is one colder.

Yes the 7173. I had electrical interference with these as well.

They are non-resistor type plugs, HUGE pain in my ass until I figured out what was wrong. These plugs cause a ton of electrical interference on all the other electronics in the car.
I ran into problems like my speedometer would randomly cut in and out when I had 4.77s and it was running through a yellow jacket and my laptop constantly going offline when I was connecting to Kmanager or AEM via USB. Someone mentioned my plugs, and when I swapped them to the BKR8EIX Iridiums, I never encountered these issues every again.
And you know its always possible that that interference was causing other issues throughout the car that I just never noticed. if it were to mess with my external wideband or OEM narrowband and throwing them off without me knowing, that could have been detrimental to my build. You never know, cheaping out on these plugs is a rookie mistake I would try to avoid.
