Description
Replace your worn or brittle glow plug harness with this Genuine GM OEM Glow Plug Harness, designed specifically for 2020–2025 3.0L LM2 and LZ0 Duramax engines. Over time, exposure to heat, vibration, and road grime can cause the factory harness to harden, crack, or lose conductivity—leading to poor cold starts or failed glow plug operation.
Restore proper function and reliability with this factory-original GM replacement, the same part used on brand new Silverado and Sierra Duramax trucks.
