Questions & Answers
Is this a genuine original part?
This is a premium high-quality replacement part designed to exact OEM specifications, offering the same dimensions and cathodic properties as the original Suzuki component.
How often should these anodes be replaced?
Anodes should be inspected during every service and replaced when they have eroded to roughly 50% of their original size. Internal engine anodes are critical as their failure can lead to engine block damage.
Does this include the mounting bolt?
This listing is for the anode block only. It requires a standard M6 x 15mm bolt (Suzuki Part # 09116-06236) for installation, which is typically reused or purchased separately.
