    Rated 5 out of 5 by from Good quality product These wires look great and so far perform as expected. The crimp tool worked fine, just follow the directions and take your time and the ends will crimp well. I used a little tuneup grease to help the boots slide easier.

    Rated 5 out of 5 by from Looks great! These wires worked great on my 89 454 suburban. The crimping tool and instructions were great. Custom cut to your exact length and bada-boom bada-bing! I like the raised 'MSD " Lettering on the boots.

    Rated 5 out of 5 by from Nice kit Very good quality. Nice tool for crimping wires. I like the added bonus for labeling wires.

    Rated 5 out of 5 by from Well made money's worth These wires will make you happy. They truly do provide a strong spark and they look nice

    Rated 4 out of 5 by from multi angle wires I purchased this set about a month ago. I find them very good quality. The one thing I found was a little difficult was achieving the desired angle. I still don't know how heat resistant the plug boots are as I don't have it running. If not for the angle adjustment I would rate them 5 star

    Rated 3 out of 5 by from MSD can do better than this What looks like a great product is lacking in good documentation. If you haven't assembled the ends on these in a while, then by the time you make it to the last one, you are likely to have it figured out. If you follow the directions for the dual crimp terminals, be forewarned that you need to count, 1, 2, 4, 5, 6, 7, 3. And realize that you will need to do some pre-crimping with needle nose pliers twice before you even use their handy tool, and then once afterward. And as much as you pay for these, you'd think they could drop in a pack of the dielectric grease that they recommend you use to get the boots to slide into place. So, good product but surely they could do much better.

    These wires are for a 396 bbc, and long enough to lay over the valve covers?
