Product Details

IMPORTANT NOTICE: If you are going to install these you must understand how they need to be wired differently and how they will respond with your current relay or pull starter. If you do not, then I suggest you purchase our complete kit with wires and instructions. If you already have the conversion done and need a replacement glow plug or you understand how to convert your series system to parallel, then you can purchase these outside of our kit. NO instructions are included.

 Mercedes Anti-Seize Compound for Use on Critical Threads

You don't need much - sold here in small air tight container


Anti-seize compound is an amazing product that can prevent frustrating and damaging thread seizure. Good quality copper based anti-seize is not particularly cheap and when you buy it in a larger tube or container it may take years to use it all... in fact you may never use it all. Since you only need a very small film on the threads the average DIY mechanic does not need very much on hand. We offer it in a air tight seal 1/2 ounce clear container with a screw lid and we only fill it half full! You may even find 1/4 ounce ends up being a lot!.
