    C-Cut Spark Plugs
    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.

    Benefits Include:
  • 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.

  • Since the mid 1980's, Accel's U-Groove spark plugs have set the standard for high performance spark plugs. Accel engineers developed and patented the U-Groove technology which permitted the spark to develop a much larger, hotter and fuller flash front. That effectively gave a more complete burn of the air/fuel mixture in the combustion chamber. Over the past 25 years engine head design and fuel management technology has changed. As a result, Accel is moving away from the U-Groove construction to the familiar ''conventional'' style ground electrode. In addition, the upper insulator will now be white instead of yellow, and available in convenient 4-packs.
    Bottom line...This one-piece construction spark plug with conventional ground electrode provides exceptional performance and value by producing:

  • Hotter Spark/Faster Burn Rate for more power at high rpms
  • Improved Throttle Response, Fuel Economy, and Reduced Fouling
  • Reduced Mis-fires
  • Purified Alumina Insulator to prevent arcing
  • Machine-rolled threads to protect heads

    Note: The last digit in the part number of the spark plug represents the spark plug heat range. 1 is the coldest. 7 is the hottest.
    Example: 111-0111-4 is the coolest plug and 111-0116-4 is the hottest in that specific style spark plug.
