Spark plugs, Which one is the L1 high tension lead, the leading plugs are the bottom two but which ones are the leading? thx

 

The L1 lead would be the lower plug on the front rotor (closest to front of car). Goes to the coil pack near the front of the car. Not to sure whice one of the two on the coil pack is L1. Should be labled. Hope this helps.

 

L = leading (lower)
T = trailing (upper)
1 = front rotor
2 = rear rotor

The leading coil is behind the headlight and its posts are labelled L1 and L2
The trailing coil is behind the strut tower and its posts are labelled T1 and T2
