MSD coils ..Any benefit or negatives ?

I've been researching these as well. I ordered a set from Amazon and will have them Friday so I will try to review them. I can't remember the website but I remember a Dyno graph that showed 9hp gain I believe. I'll try to dig up a link.

I'd be happy if they'd not catch fire or run off with my wife ... well.. at least not catch fire :P
 
I ran them on the poltergeist for roughly 10k miles or so. I didnt notice much as far as power gains. But I did also run my best et’s with them on. I will say they did smooth out my idle a ton. And as far as taking your wife. Mine is still here..........but she is pregnant
 
I was thinking about the glory days of the MSD 6AL boxes and how much of an impact their coils and caps made 20 years ago. My first car was a 1970 olds 442. I regret selling it at least once a month...
I'm looking forward to having MSD under the hood again.
 
Given the spark related problems you have had I am surprised you have not already upgraded months ago Topher.  Never heard a report form anyone saying anything other than how they run better than stock.  Seems like a no brainer.
 
I am running the MSD coils.

I noticed a smoother idle and picked up .4mpg

the power feels smoother fwiw
 
A man I respect a ton, Matt Robinson at gearhead, tested these and saw gains. There is an article for them where it shows his testing and he gained something like 5 hp, but it wasn't just peak there was a range of increases. I'll take his testing on it. I rock them on my sho and have for about a year now
 
well my old ones are OEM,  9 years old and suspect so i think i will do it. 

i will pull one off and check but im 99% sure i need the 2 pin variety.

Correct 2pin for 2010, 3 pin for 2013+
 
installed these this morning, took maybe 45min or so. way smoother idle and feels more responsive. only driven about 100miles on em so far though. just figured id update.
got em on amazon for 276~
 
I intend to get this at some point.  I don't expect much in terms of gains, but if it gets better MPG with a smoother idle then it may be worth it.
