Frequently Asked Questions
How often should I replace my lawnmower spark plug?
Most manufacturers recommend replacing spark plugs annually as part of routine maintenance, or after approximately 25-50 hours of operation. If you experience difficult starting, rough running, or poor performance, inspect and replace the spark plug sooner.
Can I use any spark plug in my lawnmower?
No – spark plugs must match your engine's specific requirements for thread size, heat range, and reach. Using an incorrect spark plug can cause poor performance, engine damage, or failure to start. Always consult your equipment manual or match the existing plug specification exactly.
What's the difference between different spark plug codes?
Spark plug codes indicate specific characteristics including thread diameter, heat range, electrode design, and reach length. Each code represents a unique combination of features engineered for particular engine types, so exact matching is essential for optimal performance and engine longevity.
