Engine anodes, also referred to as pencil anodes, are made to protect your engine block and heat exchangers. As with all our anodes, they are manufactured to the highest standards using the latest US-MIL-SPEC alloy. Our brass plugs are double-threaded so that the anode may be replaced; reusing the brass plug, and saving money and resources.

Please add the following letter designations to part numbers when ordering:
• For complete anode (assembled brass plug and zinc): (Part #) -C (example: 00-C)
• For spare anode only: (Part #) -S (example: 00-S)
• For brass plug only: (Part #) -B (example: 00-B)
