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

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 set.
