I am replacing my coil packs and when put in the original orientation as the old ones, the numbering is different.

The don't seem to be the exact same brand or type as the original BOSCH ones. Should I get the BOSCH ones?

Thanks!

 

Bosch ones aren't necessary. The aftermarket replacement ones seem to cause no problems and work fine.

 

Any thoughts about the different numbering? Im concerned about mixing up the wires / firing order.

For example, for the right coil pack, the old one reads

2 3
1 4

and the new one reads

4 1
3 2

In fact they seem to be reversed. The new left seems to match the old left and vice versa.

 

Match up position not the #'s

 

Nice thermostat mod.
