the coil packs should have numbers on them signifying which cylinder they are for. The cylinders are numbered as follows: Odds are on passenger side, evens drivers side. Lowest numbered cylinder is towards front of car and go up. Pass. side (front to back):1,3,5. Driver side (f to b): 2,4,6.

I hope that's clear enough...
