What does a closer spark plug gap do?

The larger the gap, the more voltage is needed to jump the gap. Most experienced tuners know that increasing the gap size increases the spark area exposed to the air-fuel mixture, which maximizes burn efficiency.

Designed to specific manufacturer ignition requirements, NGK’s multi-ground plugs maintain all the features of their standard plugs, including: Sorry, no automotive applications are associated with this part.

Why do I need to gap my plugs?

The ignition process is affected by increased compression, fuel type, nitrous and high output ignition systems. A plug’s gap must be adjusted to account for these changes in engine conditions and ensure a successful ignition sequence. Opening the gap presents a larger spark to the air/fuel mixture, maximizing burn efficiency.
