067007 - Miller 067007 Spark Plug for Kohler Command Engines on Bobcat & Trailblazer Welders

Reliable Ignition for Your Engine-Driven Welder

The Miller 067007 Spark Plug is a critical maintenance component designed specifically for the heavy-duty engines powering your industrial welding equipment. When your livelihood depends on your machine starting up the first time, every time, using genuine replacement parts is essential. This spark plug is engineered to meet the precise specifications of Kohler Command engines, ensuring that your welder operates at peak efficiency even under the rigorous conditions of a job site.

Over time, spark plugs can become fouled with carbon deposits, the electrodes can wear down, and the gap can widen, leading to inefficient combustion. This often manifests as hard starting, rough idling, misfires under load, or increased fuel consumption. By replacing your old plugs with the Miller 067007, you restore the electrical integrity of your ignition system. This results in a stronger spark, cleaner combustion, and a smoother running engine that responds better to the fluctuating load demands of welding and auxiliary power generation.

Broad Compatibility

This part is the designated replacement for a wide range of Miller and Hobart equipment equipped with Kohler engines. It fits the Kohler Command CH12.5, CH18, CH20, CH23, and CH730 series. Specifically, it is compatible with popular models such as the Miller Bobcat, Miller Trailblazer, and Miller Legend series. It also serves as a replacement for Hobart Champion welders utilizing the same engine platform. Verifying your engine model before purchase ensures you get the exact part needed for your maintenance schedule.

Preventative Maintenance

Regularly inspecting and replacing spark plugs is one of the most cost-effective ways to extend the life of your welder's engine. A fresh spark plug not only improves performance but also protects the ignition coil and catalytic converter (if equipped) from damage caused by misfires. Whether you are performing a seasonal tune-up or troubleshooting a rough-running machine, the Miller 067007 provides the OEM quality and reliability professional welders trust to keep their operations moving forward.
