Good quality / slow to get
I a very happy with MSD, ALL OF THEIR PRODUCTS ARE GREAT, THE PRICE IS A LITTLE MUCH FOR ME BUT YOU HAVE TO PAY FOR GOOD QUALITY. THE TIME IT TOOK TO GET HERE WAS NOT VERY GOOD, IT TOOK 5 DAYS TO GET, I GOT MY PLUGS IN A DAY AND A HALF.

like it says it does
I did not receive the straight plug boots that are pictured. I received the angled boots. I had wanted what was pictures. Wires are very long, so they should fit anything. Still haven't installed them. The video online says to use dielectric grease to aid placing the dizzy end boot on. After trying without grease, I now have to wait for grease to arrive. The kit does not have everything you need to do the job...like it says it does. Bleh.

Fantastic Wires!
These seem to be very good quality wires. The set came with everything I needed to complete the job! Engine is a 355 using an msd distributor. Truck is a 72 Chevrolet 4x4. Wires route behind the heads and under the exhaust manifolds. They allow plenty of length to put the wires where they need to be for a factory finish.

Product was used
Ordered these so I could have my plug wires cut to a custom length and add the ends myself. When I received the product the wires had already been crimped and used with numbers written on wires in sharpie plus it only came with 7 wires.. no coil wire or 8th wire for plugs. 100 dollars down the drain.
