NGK BKR7EKU SPARK PLUG

Function and technical context

The NGK BKR7EKU spark plug is an essential component of the ignition system in internal combustion engines, responsible for generating the electrical spark that ignites the fuel and air mixture in each cylinder. Its iridium design ensures precise and efficient combustion, directly contributing to engine performance, throttle response and fuel consumption. A deterioration in the spark plug results in irregular ignitions, loss of power and increased consumption, problems that in nautical applications can compromise safety on the high seas. The NGK BKR7EKU reference is designed for engines that require a high level of spark plug heat, being especially suitable in marine and outboard propellants that operate under sustained load.

When to replace this part?

The most common symptoms of a worn spark plug include difficult or failed starts, jerks and jerks during low-speed cruising, abnormal engine vibrations, and a noticeable increase in fuel consumption. It is recommended that the spark plugs be inspected at each seasonal service and replaced every 100 hours of operation or annually, whichever comes first, following the engine manufacturer's guidelines. Performing the change preventively, without waiting for obvious faults to appear, avoids breakdowns in compromised situations and prolongs the useful life of the rest of the ignition system components.
