Plug Replacement Guide Installation
To install a spark plug, turn it in as
far as possible with your fingers,
then tighten it with a wrench.
Carefully turn the spark plug by
hand into the threads until it is fin-
ger tight. If the spark plug is new,
tighten it with a wrench about 1/2
turn past finger tight. If you are
reusing the old spark plug, tighten
it with a wrench about 1/8 turn
past finger tight.
CAUTION
An improper spark plug may
have an incorrect fit or heat
range for your engine. This
may cause severe engine dam-
age which will not be covered
under warranty.
Use one of the spark plugs
listed below or equivalent.
Consult your Suzuki dealer or
qualified mechanic if you are
not sure which spark plug is
correct for type of usage.
