terminals on one of my stock coils were badly rusted so I changed them out when I did my wires. And like Toasty said they are pretty.

Well Boosty gave me a good deal on used ones so i guess its all for the better. My engine bay is a nightmare right now so nothing could make that look pretty, but maybe when all the rust and leaks and creaks and groans are gone, I can focus on dressing it up and when I do, that and a CAI will be the first things......

MSD'* DO improve over stock. A smoother idle and slightly better pull through the midrange. You can also gap larger when going with colder plugs, benfiting in a more efficient burn for the L67'* that have pulley'd down.

Hey Will, but what about a lowly NA series 1......

Smoother idle and better pull through the midrange. Just as stated above. I'm not sure why Pat is spouting no difference.

Let me clarify this.

I had one coil fail. The other two checked out perfectly. I borrowed a coil from a local member (Jseabert). It checked out perfectly. I ran them for a week or two until the MSD'* arrived. I saw and felt and heard the difference almost immediately.

I did notice a difference when I changed mine. Does a L67 benefit more than an L36?

they burn the same as a S2, and with a modded S2 to play with this summer, there was no difference in the butt dyno if a set of S1, S2, or anything else was installed, all coils had no effect in the midrange or the idle of the vheicle.....

so if a S1 coil feels the same as a S2 coil that the MSD is supposed to be exactly like, why would you spend the extra cash to have red coils?

Because the MSD is a hotter coil, Pat. It'* been known to smooth things out as I posted for some time here. Have you ever run one?

Have you ever used different coils on anything other than really old plugs and wires (as I recall, you ran your plugs and wires for FAR too long, leaving you in a position to not notice a component change to begin with).

MSD coils will be felt. I gaurantee it. ESPECIALLY on a S1.

I too am debating about replacing the coils on my "lowly" L27....I assume that since I haven't been able to find a set of 96+ L67 coils at any local yard, my best bet would be the MSD 8224s: any suggestions on where to shop for them?
