SMG Ceramic Plug Wire Upgrade

Our 8mm SMG Ceramic Plug Wire Set uses white ceramic spark-plug boots that will not melt against hot header tubes the way conventional boots can. They are built for close-clearance header installations, and they are the only plug wires we use on SMG in-house header builds. Select the SMG Ceramic Plug Wires upgrade to add SKU 9070C.
