Genuine Sinotruk HOWO Spark Plug Bushing Pressure Block - VG1238040005

Operating a natural gas-powered fleet requires extreme precision in the ignition system. The VG1238040005 Spark Plug Bushing Pressure Block is designed specifically for Sinotruk HOWO engines (such as the T10, T12, and WT615 series) to secure the spark plug bushing firmly into the cylinder head.

In heavy-duty CNG/LNG applications, vibration and thermal expansion can cause the ignition coil and bushing to shift if not properly anchored. This pressure block provides the necessary downward clamping force to maintain a gas-tight seal and prevent electrical arcing. We have observed that using substandard "soft-metal" pressure blocks often leads to premature bushing failure and engine misfires. By choosing the genuine VG1238040005, you ensure that the ignition components stay perfectly aligned, protecting your expensive spark plugs and coils from heat damage and vibration wear.
