My old outboard motor was sputtering something fierce, and a knowledgeable friend suggested I look at the spark plugs. He specifically mentioned the NGK BR8ES as a reliable and readily available option, known for its consistent performance. I needed to get my boat back on the water, and quickly, so I decided to give them a try.

Upon unboxing, the NGK BR8ES spark plug felt solid and well-made. The ceramic insulator looked clean and crack-free, and the threads were precisely cut. It had a reassuring weight to it, suggesting quality materials and construction.

I was considering a few other brands, some of which were slightly cheaper. However, after reading reviews and consulting with other boaters, NGK’s reputation for durability and consistent performance won me over. I also liked that the BR8ES was readily available at most auto parts stores, ensuring easy replacement if needed.

My initial impression was positive; I felt confident that this spark plug would solve my engine troubles. I was particularly excited about the promised resistance to carbon buildup and pre-ignition, hoping for smoother engine performance and improved fuel efficiency.

Real-World Testing: Putting NGK Spark Plugs 5422/5100.4712 5422 Spark Plug – BR8ES to the Test

First Use Experience

I installed the NGK BR8ES spark plug in my aging two-stroke outboard motor powering my small fishing boat. The installation process was straightforward, requiring only a spark plug socket and a torque wrench to ensure proper tightening. Once installed, I eagerly started the engine.

The difference was immediately noticeable: the engine started much easier and idled smoothly, without the previous sputtering and stalling. I took the boat out on the lake, where I subjected the engine to various speeds and loads. The NGK BR8ES performed flawlessly, providing consistent power and throttle response, even in choppy waters.

There were no immediate issues or surprises after the first use, just a significant improvement in engine performance. The engine ran smoother, idled better, and seemed to have a bit more pep than before.

Extended Use & Reliability

After several weeks of regular use, the NGK BR8ES spark plug continued to perform reliably. I used the boat for fishing trips, recreational cruising, and even a bit of light towing. Throughout it all, the engine ran smoothly and consistently, thanks in no small part to the NGK spark plug.

I haven’t noticed any significant wear or tear on the spark plug itself. Visual inspection reveals a clean electrode and insulator, indicating efficient combustion. Maintenance has been minimal, consisting primarily of periodic inspection and cleaning of the spark plug terminals.

Previously, I used a generic spark plug that would foul relatively quickly, requiring frequent cleaning or replacement. The NGK BR8ES has significantly outperformed that cheaper plug, offering longer intervals between maintenance and a noticeable improvement in overall engine reliability. It definitely exceeded my expectations.
