Hence, my question wasn't "what's a good plug." Though my experience with
Champions vs NGKs in my old 2 stroke bikes, I'd say the NGK will last around
5 to 10 times longer. Significant difference there. I am intimately
familiar with NGKs. However, I thought about plugs when I wasn't at my
local NGK retailer, so I bought a "like-in-kind" replacement for the
originally spec'd plugs.
My question was what's up with this? I change out a comparable plug with
the corresponding "equal," and it doesn't run at all. If they just didn't
last as long, or if my dyno tests showed a 0.005 hp loss, ok... backfires
and sputtering is a different deal completely, if you follow me there. My
car didn't come with NGKs, it came with Champion platinums. Apparently NGKs
weren't spec'd for it.
As far as price goes, NGKs ARE more expensive. However, I'm not such a
tightwad that I can't spend an extra .50 to $1per plug... that's not the
issue. You won't find NGKs around here for 1..25, even the copper
cores.... The issue IS that the Autolites were the corresponding plug, and
supposedly of comparable quality to the originals.... and for all intensive
purposes, it won't RUN AT ALL with the new plugs (yes, I gapped them to spec
also). Higher performance is irrelevant. ZERO performance is a problem. I
was just inquiring to see if anybody had experienced the same situation, or
had an idea what was going on.... kind of a learning thing. I think the
answer is "No."
