Review on 🔥 ACCEL ACC 9070C Ceramic Boot Plug Wire for GM LS Gen IV Engines, Extreme Performance by James Parker

These spark plug wires are great for LS turbo projects. They WILL NOT burn. I had a problem with back pressure due to a too small turbine. I had extremely high exhaust temperatures (this has been fixed. Too small an exhaust pipe housing on the turbo was causing overheating). I added a pair of thermal boots to them and there wasn't a single problem. My exhaust temp was so hot it melted the oil cap! 😲 Everyone survived! The white part is glass. Almost like porcelain. It's not flexible at all. They fit perfectly except for one which I had to custom wire to make due to the forward facing headers and dipstick.
