(L) on the plugs = leading - goes in the lower holes from the coil near the firewall.
(T) on the plugs = trailing - goes in the upper holes from the coil near the battery.

 

If you're going to have the car for a while, maybe next time use platinum leading plugs & you won't have to change them as often.

Rotaries EAT steel leading plugs.

 

Trailing
O
P


Leading
O
W
E
R


L1 and T1 means its the first rotor aka. closest to the front of the car.

L2 and T2 are the second rotor aka closest to the firewall.

L1 = Leading #1
T1 = Trailing #1

L2 = Leading #2
T2 = Trailling #2
