Hello, I just bought some msd blaster 2 high vibration ignition coils and my question is are they just plug and play or is there anything else i need to do before installing them on my 12a? I tried looking on the FSM but couldn't find anything in regards to it.

 

If you search for TFIDFIS you'll find quite a few good links for ignition upgrades. I would read those threads and just install that setup. Especially since you just bought blaster coils. Fairly straight forward.

 

The answer is no. Just install like the fatory ones.

 

No different from stock if they are canister type coils like the stock ones. Some don't like being mount sideways and may leak, not sure about the blaster coils.

 

I've been running MSD Blaster 2 coils in the -SE for about 10+ years in the stock position without any problems at all. They're good to go to install where they belong,

 

I have two MSD Blaster 2 coils in stock position on my SE for 10+ years without issue too!

 

Thanks everybody who commented, disconnected the old ones and put the new ones in and can definitely feel a difference. Now on to my rough idle issue haha.
