Genuine Sinotruk HOWO Ignition Coil Protective Bushing - VG1238040104

If you are operating a Sinotruk HOWO truck with a natural gas engine, you know that ignition precision is everything. The VG1238040104 Ignition Coil Bushing is a small but indispensable component designed to shield the ignition coil and ensure a perfect seal within the cylinder head.

In the high-heat environment of a heavy-duty gas engine, standard rubber bushings eventually become brittle and crack. A compromised bushing leads to electrical "leakage" or arcing, which results in engine misfires, poor fuel economy, and unnecessary stress on your spark plugs. This genuine VG1238040104 bushing is manufactured from a high-grade silicone-based composite that maintains its elasticity even after thousands of hours of operation. Choosing this OEM part means you are protecting your ignition system from moisture, dust, and heat-related failure, keeping your fleet on the road and out of the repair shop.
