14mm Thread, 3/8'' Reach, 13/16'' Hex, Gasket Seat - Projected Tip. ACCEL has improved the ignitability of the spark plug in a new design! ACCEL has always utilized unique electrode grounding designs to improve combustion and create a larger spark. Allows spark to expand directly above the midpoint of the electrode core - preventing the spark from being shrouded by the ground strap. Gives the flame an unblocked area to grow - creates a larger flame front for a more complete burn.
Reduces excess heat absorption of the electrode and ground strap, also known as the''quenching effect'', which leads to misfiring, rough idle and overall poor performance. Produces a larger spark nucleus without having to increase the spark gap. Creates a more complete burn of the air-fuel mixture resulting in -Increased performance, improved throttle response, greater fuel efficiency and reduced emissions. Shorty design can solve Spark Plug to header clearance problems, helps end burning plug boots, needing to dimple headers for clearance and improves spark plug socket access.Suits the following models, and more.
