Indmar GM Distributor Cap for HVS system
Restore strong spark delivery and reliable ignition performance with the Indmar HVS (High Voltage Switch) Distributor Cap. Designed for 8‑cylinder applications, this molded, high-dielectric distributor cap helps route high-voltage ignition energy cleanly from the coil to each spark plug wire tower for smooth starting, stable idle, and consistent power under load.
The cap features clearly numbered plug-wire towers (1–8) and a central coil connection tower to reduce misrouting during service. Its durable, heat- and vibration-resistant molded construction is built for harsh engine-compartment conditions and provides dependable insulation to help minimize crossfire and arcing.
