Frequently Asked Questions
How often should I replace my spark plugs?
Replacement intervals vary significantly based on the plug material and engine type. Copper plugs may need replacement every 30,000 miles, while iridium and platinum plugs can last 80,000 to 100,000 miles. For small engines, check the owner's manual, but typically every season or 100 hours of use.
What does 'fouling' mean, and how can I prevent it?
Fouling occurs when deposits (oil, carbon, or fuel) build up on the electrode, preventing a strong spark. This usually indicates an underlying engine issue (like rich fuel mixture or oil burning) or using a spark plug that is too 'cold' for your application. Using the correct heat range plug is the best prevention.
Are multi-pack spark plugs better than single plugs?
Multi-packs (like the Champion 4-pack or NGK 6-pack) are generally more economical and convenient if your engine requires multiple plugs (V6, V8, or multi-cylinder marine engines). For single-cylinder applications (like many lawnmowers), a single pack might suffice.
