I'd start with the BPR6ES's. Or, BP6ES's, if you can find them. The "R" means
they're resistor plugs. With NGK's, the lower the number the "hotter" the
plug, and vice versa, the higher the number, the "colder" the plug. On street
engines, I've had good luck with the BP6ES's.

Subject: NGK sparking plugs ?!
Hello spridgets,
the guy who rebuilt my engine (thanx Paul A.!) installed
Autolite 64 sparking plugs.... .. i think i'de like to try some
NGK's as i hear nothing but good about them... the installed
plugs are AUTOLITE 64. i just did a cross reference from that to
NGK and got the following:
TRADITIONAL PLUGS;
BPR6ES
BP5ES-11
BPR5ES
BPR5ES-11
BP5ES SOLID
BP6ES-13
BPREY SOLID
V-POWER PLUGS;
GR4
GR5
ZGR5A
BPR5EY=11
BP5EY
SUPER CLASS
BPR5EV
the question is, which NGK plug to use from all this..?
the engine is a 1098 with a mild cam, pertronix, K&N's with
stacks. no other mods.
??????????????????????????
