High-Quality Engine Ignition Wire Set for GM Optra

Premium copper-core conductors ensure superior conductivity and minimal resistance for consistent spark delivery. High-grade silicone insulation resists heat (up to 500°F) and corrosion, extending lifespan in extreme engine conditions. Precision-molded boots provide airtight seals, preventing moisture ingress and misfires.

Direct-fit design for GM Optra 1.8L engines—no modifications required. OE-compatible connectors guarantee seamless integration with factory ignition systems. Ideal for performance upgrades, routine maintenance, or replacing worn OEM cables.

Batch-tested for voltage endurance (40kV+) and EMI suppression. Reinforced shielding reduces radio interference for cleaner engine diagnostics. Sold in bulk at unmatched wholesale pricing—stock up for fleets or retail resale.
