SMG Ceramic Plug Wire Upgrade

SMG 9070C 8mm ceramic plug wires use heat-resistant ceramic boots that will not melt against hot header tubes like conventional boots can. They are the only plug wires used on SMG in-house header builds. Choose SMG LS MLS gaskets, 9070C wires, heat wrap, or the available combinations. LS swaps only; race-use product.

Processing & Shipping Overview

Processing occurs before shipping.

Most in-stock items typically process within 2–3 business days before shipment or pickup. Expedited shipping options affect transit time after an order ships and do not speed up processing.

Made-to-order, special-order, vendor drop-ship, and freight items require additional processing time before shipping. Any extended lead times will be noted on the product page when applicable.

For the most up-to-date order status or lead time questions, please contact sales@smgspeed.com or use live chat during business hours.
