These Accel wires are the greatest spark plug wires I have ever owned. They look and perform perfectly.

Decent plug wires.
I had to recrimp a couple factory ends which the wire pulled right out of the terminal and the boot. So that sucked. Once I fixed those I moved on to laying out all my wires nice and neat and started terminating my ends. Having both sets of plug ends included is nice since I’ll eventually be switching to a Holley hyperspark which has the different plugs. Also get a can of silicon lubricant to make sliding the plug wires through the boots a breeze. I just spray down the inside of the boot and start pushing wire through.

Perfect fit every time
I've used probably eight sets of these over the years. They're the only spark plug wires I buy anymore. If you plan on doing multiple sets its well worth the money to buy the proper wire assembly pliers.

Perfect for IH Scout
I used this on the 392 in my Scout with the Holley distributor. It comes with cable ends for either the Holley distributor or the Prestolite. The wires were all long enough to cut to length and route the proper way.

Whatever the cause, these worked really well.
I bought these because the silicone boots fully cover the spark plug insulators. Great for air cooled engines where dust and grime can create leakage paths across the insulators. I installed them on an air-cooled VW and, to my great surprise, the engine seems to have more torque. The engine has a top-of-the-line Bosch coil and electronic points so perhaps the regular cables couldn't handle the increased voltage? Whatever the cause, these worked really well.

Good wires but I did not have a super smooth experience.
They’ll get the job done, nice high quality wires but they’re a bit short for certain engines. I have a Cadillac 472 in my Fleetwood, the wires were almost too short to fit in the way I wanted, but I was able to make them work, probably would work better for a small block. Also they tend to slide off the spark plugs, so I have to push them back to reseat them every so often, but that might just be because the wires a little short.

Great quality!
Used these in my Harley after moving the coil location. The boots fit extremely tight, used wd40 to help slip them over the wire. Comes with two different style ends for the coil.

Buen material pero insuficiente, los cables se supone son para ajustar el tamaño y son muy cortos en lugar de llegar 8 llegaron 6 lo mismo con los capuchones llegaron menos de los necesarios, todo mal con el producto, lo devolví y estoy en espera del reembolso
