These wires are the same ones used by many NASCAR Cup teams and other professional racing circuits including ASA and Daytona Prototype LSX engines. Made locally for us in Race City USA.  Stainless steel spark plug terminals connect to wire-wound suppression cores, all wrapped in a 10mm high-temp silicone/fiberglass sleeve (rated at 30 Ohms per foot).  45 degree spark plug boots, 90 degree boots at the coils.  The perfect length and angles to provide excellent clearance around headers.

These wires are a little more difficult to install than others but they are built to last in extreme conditions.  We recommend not using Die-electric grease to install.  Instead use dry lithium or dry silicone lube.  Install by the wire not the boot. Available with or without insulating fire sleeves.  Call for custom applications & lengths.

    I just wanted to say that these are the beefiest and of extremely high quality. Not to mention they look amazing. I had a set of msd wires that burned through a few weeks after I installed headers and had a ton of misfires. I put these on in April and since then my misfires cleared up and I seemed to of gained an extra mpg or 2. These wires added with their heat socks is a solid combo. As always PCMofNC delivers!

    These are the beefiest wires your going to find. They make msd look puny. Friendly service, great price, and a quick delivery. You can’t beat pcm of nc.

    I left the first review on these wires and just wanted to update almost 5yrs later. Still running the same wires and socks and they are still working great. I’ve had them off and on several times over the years and they have never tried to break on me. Socks are a bit stained up and have a few thin slots from resting on the headers, but still functional.
