• Low resistance: 40–50 ohms per foot—among the lowest for helically wound wires. MSD Ignition

• EMI suppression: Ferromagnetic-impregnated core acts as a “choke,” containing electromagnetic interference inside the wire. 

• High-quality insulation: Silicone / synthetic jacket resists heat, abrasion, and oil exposure.

• Dual crimp stainless steel terminals: One crimp secures the jacket; another secures the conductor—ensuring reliable electrical & mechanical connection. 

• Precut length: Designed specifically for the LT engine layout in C7 Corvettes—wire lengths approx. 8–8.5 in (varies by cylinder) 

• Color & style options: Commonly offered in red or black finishes. Bendable boot tips: The boots can be bent up to ~45° for clearance where needed, but don’t exceed that to avoid damaging wire integrity.
