I read it somewhere. Is it really bad for stock opti? If so, what coil should I go with?

 

No, it's not bad. Just some smoke somebody is blowing.

 

I believe the first productions a many years ago might of had issues, but not now.....

Just like their OPTI now..... Issues???? Yes and no...

 

hmm theres always nay sayers but **** it

MSD 6AL - Ebay $175
MSD Wires - Ebay $80
MSD Pro-Billet Opti - Ebay $422 (Did a GM Opti + MSD Cap - Rotor the GM failed after 600)
MSD Blaster Coil - Ebay $50

sure $722 might sound like alot but these are quality parts

Car has unbelievable spark-ignition and throttle response

I rest my case

 

I didnt think so either. just wanted to make sure.
