What made you choose this particular product?
I am using three of these coils- one runs the trailing plugs through a 12A electronic distributor, and one for each leading plug through a 6AL-2 box.
Is this your first time buying from this brand? Did you consider other brands?
I've had MSD products on a bunch of vehicles- good, reliable parts.
Was it easy to install? Any installation tips that will help others?
I made a bracket on the firewall for the three coils to sit.

Was it easy to install? Any installation tips that will help others?
Very easy. Remove Ignition covers 2 bolts each side. Unplug then slide old ones out. Dielectric grease the ends and put the new ones in, plug them in and replace covers and bolts. Took 15 mins max.
Once you've had a chance to use the product, did it meet your expectations?
I had a hesitation but car wasn't throwing any codes. Replaced these and hesitation is gone and car pulls like a freight train again.
