Spark plug type

In Simple Terms

F1 engines must use standard spark plugs that create a spark by electricity jumping across a gap. This means no fancy alternative ignition systems are allowed - just the conventional technology that's been used in engines for decades.

• Only conventional spark plugs with exposed gaps are permitted
• Electrical potential discharge across the gap is the required ignition method
• Alternative ignition technologies are not allowed
• This ensures all teams use the same basic ignition technology
