I'm putting in an EGT gauge and was wondering which cylinder is #3, because I have been told that it runs the hottest? Also, where is a good place to run wires through the firewall, so I can hook the gauges up? Thanks.

three is the drivers side back cylinder. the best place to run wire is drivers side below the brake cylinder.

 

#3 is the passengerside rear not the drivers side. You can also see the order on the coil pack where its labelled.

 

Um, correct me if I'm wrong on this, but the Cylinder which has the most problems is the one closest to the turbo, where all the heat is generated. That would make it the one closest to the firewall on the passanger's side. If that makes it number 3, then so be it. (Sorry, don't own a WRX at the moment to know that kind of stuff.)

 

At the front on the passengerside its #1 then the front drivers side is #2, rear passengerside is #3 and rear drivers side is #4.

 

yep. i was looking upside down.
