C-CUT SPARK PLUGS
• 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.

U-GROOVE SPARK PLUGS
U-Groove performance spark plugs produce a larger spark for more power at high RPMs. Improves throttle response & fuel
economy, less fouling. Purified Alumina insulator prevents arcing. Machine rolled threads protect heads. 035 gap.
• U-Groove designed for spark delivery
• Copper core utilized for maximum spark

SUPERSTOCK 4000 SERIES SPARK PLUG WIRE SETS
ACCEL’s SuperStock 4000 series spark plug wire sets are designed to upgrade an OE ignition system for high-spark delivery
levels for street driven applications. The 450° F rated silicone jacket is extruded over a tightly woven, rugged fiberglass braid.
The braid is applied over high dielectric strength EPDM (Ethylene Propylene Diene Monomer) inner insulation for ignition wire
performance that exceeds SAE specifications.
Features Include: • 8mm yellow, red, black, and blue silicone jackets • Orange and color-matched blue, red, and black
• Street-driven applications silicone spark plug boots
• Pre and post-HEI vehicles
