Spark Plugs

Post by Bill »

Went to my friendly neighborhood advance auto to get spark plugs. they
gave me NGK BPR6ES. I thought I read on here that those are wrong.
Is that correct? Never have got a hold of plug wire either. Thanks,
Bill in Missouri

Think those(B6ES) are a hotter burning plug than stock, you want to
get NGK B8ES(original ones) or B7ES(slightly hotter)

actually on ngk's website the 6ES is listed as the part for the engine,

The BPR6ES has an extended (P for protuding ?) centre electrode, so
before using them you need to make sure they won't come in contact
with the top of the cylinder !
The R means there is a resistor built in to reduce radio interference.
Might cause a weak spark if the rest of your ignion system is not in
peak condition.
The 6 is the heat range, and is a 'hotter' plug than the original
B8ES. This means the sprak plug runs hotter, which is normal for a
water cooled engine, but air-cooled engines tend to run a hotter
combustion chamber, so need a 'colder' plug, hence the B8ES. Using
the '6' heat range can lead to the spark plug over heating and in
extreme cases, the centre electrode can start to melt.
Stick with what Honda recommends, they spent a lot of time choosing
the right plugs for the engine. The '7' is good if the engine is only
used for short trips or running in a very cold climate, as the plug
will reach its operating temperature quicker.

BPR6ES are very hot resistor plugs. B8ES is the normal plug, B7ES is
hotter and B6ES is what you would run if you are fouling
plugs/burning oil etc, but be cautious as you may burn a hole in a
piston especcially if the timing is too far advanced.
