JDMSPEED LSx LS1 LS2 LS3 LS6 LS7 High Heat Spark Plug Ignition Wires Set 10.5mm Replacement Review

When disconnecting the spark plug cables, grasp as close to the block as possible, otherwise you will pull the cable right out of the connector. Otherwise there are no complaints, after assembly 3 of 8 everything is fine

Seems well made and can take some heat. Installed with header download and has been running for about a month with no problems. Some clicked on install and some didn't, for which I deducted a star.

Looks great, works great BUT a few ends broke in the spool when removed. A simple twist and pull removes the wires. I never had a wire to do this. I bought another set but wanted to share my experience.

Put them on my LS swap and without the insulating sleeves you can clearly see the difference between these and MSD. Manifolds are fine as long as you put insulating sleeves on them, but you can buy a new set of manifolds without insulating sleeves within a week.

A mechanic friend of mine worked as an electrical engineer on jet planes before returning to be a car mechanic. He checked my wires before I put them on. He was impressed. Good product, good price and good seller. Walked into my 65 El Camino, LS. I've since bought another kit for the store's truck. Go to the wires. Joe Kalamazoo

This is decent/very good. I installed them on lm7 with ict truck coil brackets and 1 7/8" headers for Chevelle. This kit has lasted about 1200km, not the best result. They failed because the wires became very very brittle when overheated and 2 of them completely broke in half. All the others were in perfect condition and I still keep them as spares. but if the plug cord breaks in half. you're kind of stuck. I recommend either buying 2 sets and spares for to have on hand, or simply buy a quality

After reading all the reviews, it's obvious what most customers don't realize: With a big engine that has headers, it doesn't matter how much you spend on headers, they don't last long if you don't replace them . Protect them from the heat, they won't last very long meaning you'll spend more on metal boots and high temp boots that run on wires. Another trick is to use a header wrap over the boot, the superglue holds it so well you can use the header wrap instead of the boot. Speaking from…

I was very skeptical to buy them at first because I believe in "you get what you pay for". In this case I was wrong. In terms of packaging, they come in a sealed plastic bag inside a cardboard box. I immediately tested them for stability and was very impressed. The product is very well assembled and none of the individual wires differ in size from each other. I have not noticed any connection issues (click or no click) when installing these connector cables. The angle at the end of the plug…
