How much Do MDS coils Help? well i have an offer on the table to buy a set of MSD coils brand new pretty much.only used about a week,then the guy melted some pistons.anyway he said he will sell all 8 to me for 250$. my questions is should i buy them?how much will they help?im saving for a stall and want to get that soon also,but i know how much these coils are new,so should i buy them or save my money and get my stall and tune?, and say screw it.? help
From what I've read on these forums, aftermarket wires and coils are pretty much a waste of money; the stock stuff works fine unless you're making mega-power and are trying to squeeze every bit out of your setup. Save up for that stall...
You actually lose power by switching to the MSD coils. Heres how.
What the MSD's are in perfect working order, there is no power gains.
But! They like to fail at random and intermittently. This usually results in a misfire in that cylinder or multiple cylinders.
Misfires equal power loss.

Mike @ G-Force was telling me about a test they ran on a twin turbo C5.
Only change between runs was changing from stock coils to MSD.
Stock coils was 601 rwhp @ 7800 RPM
MSD coils was 601 rwhp @ 7800 RPM
Waste of time and money!

Thats what I did and they look much better but I have heard people say that the paint may make them overheat?? I hope not cause I'm not taking it off.
I still cant believe how much they want for them! and to get absolutly no gain in performance

stay with the stockers. my car had msd wires on it when i got it about 2 years ago and i did a few plug changes and a few of em just wouldent snap on right any more and i live in a tiny town so i had to get some auto zone duralast wires then i went to the track the next day and ran the best run to date(12.6@110xx)
so i really dont think they do any thing maybe on a high boost car that has trouble keeping the spark going.

2nd on the wires....... i had a set on my 94 and with 198,000 miles when i sold it, the wires gave it a little boost. nothing dramtic or super bad, but there was a little something. they were maybe the 3rd up grade i did to my 2000
