Santa just arrived in a big brown truck, got my coils.  I ordered from Rockauto.com.   Not super fast but dependable and fair pricing. 

 

It was my fault for not having a spare on hand - dumb.  Never had an actual coil/igniter failure before if you don't count the ballast resistor failure on my early 2nd gen installation.  They are generally very reliable.  I'm wondering if I have them located in a 'too hot' location.  I used a blast tube on the 2nd gen coils but thought that I was being too conservative so deleted that on the Renesis installation.  May have been a mistake.

Tracy, Pardon my ignorance but what is the ignitor? The coil I understand, is it a capacitor or other device?
