I've used these wires on several different engine builds and consider them the best!

Great wires, good directions and full kit. Not easy to slide boots on at all. Use lube.

The wires that did show up were fine but were missing a wire, and the bag with the ends on them was open and missing parts. Ordered a replacement and the same issue happened.

These are exactly the part number listed for sale. Msd makes the best wires. These cut to length kits are great for marine applications where longer than normal length is needed. Ignore the bad reviews that thought these were another product. Those people need to learn how to read, and accept their own mistakes. I love the black wires too!

Great. Be sure to test the resistance with a meter.

These wires are great, performance increased throttle response! If you have a high performance engine/ignition set up you will be happy with msd Yes you have to cut and crimp...so what spend an hour, and have perfect fit wires. My other accel wires were a year old i threw them out half melted....

OK FIRST OFF THESE DONT COME COMPLETED SO YES YOU HAVE TO CRAMP EVERYTHING WITH IT PLUS MEASURE THE LENGTH OF THE OLD WIRES TO GET THE RIGHT SIZE. I JUST DIDNT WANT TO SCREW ANYTHING UP SO I JUST THEM BACK. NOT WORTH THE TROUBLE. WISH MSD WOULD ACTUALLY FINISH WHAT THEY STARTED.

MSD is a great company once you get to view the video support on the technical side. I was not pleased with my contact on the parts side. The picture shown at Amazon, even after I entered my vehicle type to include engine, did not describe the product. In fact, the plug cables I received were not assembled as shown and the rotor did not fit the distributor shaft for a 302 Ford engine.
