Critique the condition of these spark plugs please

Just be aware that the BP6ES only comes with a non-removable screw on tip making it unusable. The Resistor plug (BP6ESR?) I think is available but you don’t want more resistance. If you find the BP6ES be sure and ask if the tip is removable.

You need to look on ebay for the BP6ES and BP5ES, they stopped making the non-resistor version. Both were availalable with the screw off tip, you just have to make sure it's the right code number, I've bought plenty and have some now. I use BP5ES for city driving in hot weather so you may want to give them a try. Also beware that many vendors will list BP 5 or 6 ES and ship you the resistor version so confirm before buying amhik. Here is a removable tipped BP6ES:

I need new plugs and am wondering if I should go with hotter BP5ES, I have some oil fouling with BP6ES plugs and don't run my coupe enough to burn the deposits off. Would a hotter plug be a good idea?

i can not tell,

maybe @Stevehose could help

regards
