10.5mm Spark Plug Wire Set,9pcs High Performance Spark Plug Cables Compatible with SBC BBC HEI 350 383 454 Electronic

Not sure why they sent 9 wires since no coil wire needed on HEI systems but what the heck. Wires look great and seem to work well. They have a large diameter and will not fit into regular sized wire holders. Perhaps there are holders made for this size wire but I just routed and held wires by alternative methods. No issues so far with performance.

Good quality. Strong. Well made. They are just a little thick so if you are using factory wire holders it might get a little tight. I'm super happy with them. And the color was just what I wanted

Bought these for my 84 C10 350. Great price. They're all a little short. Hard to organize the way I want. I included a picture of how they look installed. While I buy some 10.5 organizers. Which brings me to my 2nd picture and fair warning to the cheap like me. You cannot squeeze these into your old 8.5 organizers it will cut through them like a razor blade luckily it comes with 9 wires.

I feel the insulation was very very thick,.... but in my oppinion it helps when your insulating sumthing worth Insulating. After about a month of running these plug wires I ended up removing them and just buying the "middle of the road" plug wires at O'reillys... runs so much better!!!!... I still have these hanging on the wall in the shop incase I need one in a pinch or sumone else for that matter but I wouldn't use these as my primary set... I'm not completely dissatisfied but I'm not overly impressed with them either.

They were not long enough if I used units in holders. But feels like great wires. They worked great. But no coil wire....ok where’s my coil wire?

They look ok. Not sure how long they will last. I will update after I put tbem on and tested them out.

Bought for an old beater plow truck , better price than custom set and fit nice on an 86 305

These are no good at all. There is no coil wire and no heat resistance at all. I had one burn up while another brand wire next to it was only lightly scored. They don't fit well. No comfortable "snap" on the distributor or plug and way too easy to remove (shake loose). I returned them.

just what I needed
