Spark Plugs
5. Torque the spark plug. (If you do
not have a torque wrench, tighten
the spark plug two-thirds of a turn
after it contacts the cylinder head.)
Tightening torque:
13 lbf.ft (18 N.m, 1.8 kgf.m)
Tighten the spark plugs carefully. A
spark plug that is too loose can
overheat and damage the engine.
Overtightening can cause damage to
the threads in the cylinder head.
6. Install the spark plug cap.
7. Repeat this procedure for the
other three spark plugs.
U.S.: Si, Canada: Si-R
Reinstall the plug wire cover, and
tighten the four nuts.
