Upgrade your Engine Performance with JDMSPEED New 10.5mm Spark Plug Wire Set Replacement for HEI SBC BBC 350 383 454 Electronic Review

I will change my rating if they don't help me. Installed on 3/7/19

Second, to keep it or any of the wires on the distributor cap, they need to be cut about 1/4 inch or they'll pop out right away. Third, all the wires are too long. I had to find a way to keep them out of the sewers. I don't mean just an inch long, I'm talking over 6 inches on some of them. I've been working with cars for fifty years and I've never seen a set like this. replace as usual, either they sent…
