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

Kept burning straight style wires, and others were sketchy close to the exhaust.Love these, no more misfires.

Just put these on my 2000 Trans Am with a built ls1 with headers. Just a tad longer than perfect but not a problem as these fit more applications. They're very thick compared to stock and the Jegs Pow'r wires which were also nice but had straight plug boots where these are angles making these a lot better if you're running headers. I highly recommend them for quality and cost!

Been running them on an LS swap with headers for about a year now. They have heat sleeves, but these are still perfect underneath. No drying or cracking. I’d buy again for sure

Seem to be very well made and heavy duty.

These are poor quality and last less than 4 months. Even when you buy the heat shield boot to go over them. Save your money and time skip these and go for the Michigan plug wires. When we removed them they were just falling apart.

Looks great length was just what I needed

Make sure to be careful when plugging them in. The inside connectors can bend and not slide over plug. Check to make sure they’re all straight if not use small screw driver to bend straight. And carefully insert them making sure it’s snug on the plug.

Works well at a reasonable price
