What coil?
 

My rear roter trailing coil isnt firing anymore. What should i replace it with? another stock coil or might it be cheaper/beneficial to wire in an aftermarket one?

About how much does a stock replacement cost (new) ?

also post 900 :)

I'm sure Ray at Malloy will be a little cheaper but that's about what you can expect to pay.

ouch, anyone try putting an msd coil pack in their car?
