Description
Efficient Ignition: Our marine spark plugs feature good conductivity, efficiently transmitting ignition current to ensure ample energy during engine ignition. This effectively boosts engine power output while preventing ignition delays or instability. The product guarantees reliable ignition even under challenging conditions, maintaining stable engine operation.
Secure Connection: Our marine spark plugs feature tightly fitted connectors. During rough seas or vessel movement, they remain firmly secured at the spark plug-to-coil interface. Vibration won't cause loosening or poor contact, preventing engine stalls due to interrupted ignition. This ensures continuous, stable engine operation during navigation.
High Quality Material: Our marine spark plugs are crafted from high-quality silicone material. This silicone material offers good aging resistance and insulation properties. Under prolonged operation of marine engines, it effectively prevents wire damage, ensures stable current transmission, and avoids issues like electrical leakage.
Wide Application: Our marine spark plugs measure 6 inches in length. They serve as a direct replacement for OEM part number #18-8816-1 ZF478V. If your marine engine previously used this model, simply swap it out for immediate use. Regardless of your boat's make or model, as long as the specifications match, these plugs will fit.
Easy Installation: Installing our marine spark plugs is straightforward. First, shut off the engine and allow it to cool. Remove the old spark plug wire. Then, securely connect one end of the new wire to the spark plug connector and attach the other end to the corresponding position on the ignition coil. Finally, check that all connections are tight. No complex tools are required throughout the process, allowing even beginners to complete installation quickly.

Common questions about buying open-box and refurbished.
Why buy refurbished or open-box?
Refurbished and open-box products offer the same performance as new at a fraction of the price. You're already saving $2 on this listing. They've been inspected, tested, and are ready to use — the only difference is the price tag. Buying refurbished also reduces electronic waste, extending product life cycles and keeping functional devices out of landfills.
What's the difference between open-box and refurbished?
Open-box products are customer returns that have been inspected and confirmed functional. They may show little to no use — often the item was returned simply because the buyer changed their mind. Refurbished products have been professionally repaired or restored by technicians, tested to meet or exceed manufacturer specifications, and sometimes come with a warranty. Both are a smart alternative to buying new.
Why use OpenBoxFox?
Finding refurbished deals is time-consuming — you'd have to check Amazon Warehouse, Reebelo, Dyson Outlet, and others separately for TNAIYH products. OpenBoxFox aggregates these listings in one place, so you can compare and find the best deal without the legwork. We update pricing daily so you always see current availability and real savings.
Is it safe to buy refurbished?
Yes. Products listed on OpenBoxFox come from established retailers like Amazon, Reebelo, and Dyson — not unknown third-party sellers. Each retailer has buyer protection policies, return windows, and in some cases warranties. You get the price advantage of used goods with the purchase security of a known retailer.
