High Performace Wires

Exactly as described, great kit.

Still the best

I've tried a bunch of plug wires over the years but keep coming back to the MSD 8.5mm. The boots are a high grade of silicon that does not dry out or burn even close to headers. The terminals are double-crimped (one crimp over the insulation to hold it firmly, a second crimp for the conductor). I've not seen double crimps on other brands, they fold the conductor back over the insulation and crimp the whole thing with a single crimp.I also like that the distributor terminal has a very positive "click" when installed. It really holds it firmly, much more so than other brands.

Nice Wires

They require work, obviously, and while the assembly is time-consuming, it's nice to have a custom product when you're done. And that's not mentioning the quality of this plug wire set - really, really nice. 8.5mm are really the best you can get and better than most applications need, but they really pair well with upgraded ignition systems or high voltage set-ups. Oh, and PS, they include nifty little wire numbers to loop around each wire - string those on before you crimp the distributor end of each one! ;-)

Good product

I have used these wires for close to 20 years now and they always work great. My only complaint is that this is my first set that didn't come with stickers.

MSD score's a big home run again !!!

I love MSD products and this one here has solved my needs perfectly. I am readying a 400 SBC for my 69 C-20 and everything has went with out a hitch. Cutting and measuring was a snap with the engine out on the stand. The quality of these wires is second to none and the instructions are precise and easy to understand for any handy person looking to upgrade their ignition for top performance.I am including a few pictures of this install for anyone ready to make this change. Buy with confidence.RagenRat

can't be beat.

It's hard to beat MSD products. They work on the track and on the street.

For the amount of money, MSD should include everything needed!

I love the construction of these wires, however, I think the "custom length" approach saves MSD money and time, but not the end user. Not all of these cables are the same length. They are pre-cut to match the distance of each cylinder to some degree. Why not just put the boot on then? Or provide everything necessary to complete the job! There's no way you can assemble these wires without a vise/crimper, and some type of lubricant to slide the boot on, so the customer is required to spend more money. At the minimum include the lubricant to aid us in getting the boot over the crimp, without increasing the price. I'm not someone who has not assemble these cables before. It is a process, and in some cases can be a pain.

Easy cut, crimp and boot!

Easy to cut, crimp and boot giving you a custom fit. Have enough left over for my sleds and motorcycles too!I did not use a table vise, i used a battery/slip lock pliers and worked great plus much faster.
