Optimized for Superior Engine Performance and Longevity

The Quicksilver BR7HS is designed to deliver a powerful, consistent spark under all operating conditions. This translates directly to tangible benefits for every boater:

* Effortless Starting: Experience quick and reliable ignition, whether your engine is cold or has been running for hours. The advanced electrode design ensures a clean, powerful spark that minimizes starting effort and reduces strain on your battery and starter.
* Smooth Operation: Achieve smoother idling, crisp acceleration, and consistent power throughout the RPM range. By promoting complete and efficient combustion, this spark plug helps your engine run at its absolute best, reducing hesitation and rough performance.
* Enhanced Fuel Efficiency: A clean, efficient burn means less wasted fuel. By optimizing the combustion process, the BR7HS spark plug can contribute to improved fuel economy, allowing you to spend more time on the water and less at the fuel dock.
* Reduced Fouling: Built to resist carbon buildup, this plug maintains its performance for longer service intervals, even during extended periods of trolling or low-speed operation. This anti-fouling characteristic ensures consistent reliability season after season.

Engineered for the Harsh Marine Environment

Unlike automotive spark plugs, the Quicksilver BR7HS is built from the ground up to withstand the unique challenges of marine use. Its robust construction features an advanced metal shell plating that provides exceptional protection against corrosion and rust caused by saltwater, spray, and high humidity. This superior corrosion resistance not only extends the life of the plug but also prevents it from seizing in the cylinder head, making future removal and replacement a hassle-free process.

Furthermore, the integrated resistor in the BR7HS design is critical for modern boats. It effectively suppresses radio frequency interference (RFI) that can disrupt sensitive onboard electronics, such as GPS, fish finders, and VHF radios. This ensures all your vital equipment operates without static or interference, providing a safer and more enjoyable boating experience.

As the original equipment manufacturer for Mercury Marine, Quicksilver parts are held to the highest standards of quality and durability. Each BR7HS spark plug undergoes rigorous testing to ensure it meets or exceeds factory specifications. When you choose Quicksilver, you are choosing the exact same quality and performance trusted by the engineers who designed your engine. Equip your motor with the Quicksilver BR7HS spark plug and power your adventures with confidence
