Spark Plug - Suzuki LT-A450X 2006 Owner's Manual

SPARK PLUG

Your vehicle comes equipped with an
NGK CR6E or DENSO U20ESR-N.
To determine if the standard spark
plug is right for your usage, check the
color of the plug's porcelain center
electrode insulator after vehicle oper-
ation. A light brown color indicates
that the plug is correct. A white or
dark insulator indicates that the
engine may need adjustment, or
another plug type may be needed.
Consult your Suzuki dealer if your
plug insulator is not a light brown
color.
CAUTION
Failure to use the proper spark
plug can damage your ATV.
An improper spark plug may have
an incorrect fit or heat range for
your engine. This may cause
severe engine damage which may
not be covered under warranty.
Use only the spark plugs listed
below. Consult your Suzuki dealer
if you are not sure which spark
plug is correct for your type of
vehicle usage.
NGK DENSO
CR6E U20ESR-N
CR7E U22ESR-N
NOTE: If the above-named plugs are
not available, consult your Suzuki
dealer.
To install a spark plug, turn it in as far
as possible with your fingers, then
tighten it with a wrench.
CAUTION
Improper installation of the spark
plug can damage your ATV.
An overly tight or cross threaded
spark plug will damage the alumi-
num threads of the cylinder head.
Carefully turn the spark plug by
hand into the threads. 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.
