Detailed Description

Spark Plug; U-Groove; Header Plug; Pack Of 8;

ACCEL's patented race proven spark plugs in a shorty configuration. The overall length has been reduced 3/16 in to 3/8 in (depending on the specific spark plug) to gain critical air gap between the spark plug boot and the exhaust manifold or header tube. This helps eliminate burning the spark plug boot or dimpling the header tube. The shorter spark plug length also can make it easier to install and remove the spark plugs in certain applications where there is not a lot of room to fit a socket or move a wrench around.

  • Shorty spark plugs for tubular exhaust headers
  • Eliminates dimpling headers for added clearance
  • Improves spark plug access to fit socket or wrench
  • Shorter overall plug length vs. OE style plug
  • Copper core center electrode
  • Projected tip
  • Helps eliminate urned spark plug boots.

Accel's U-Groove was developed to meet the demand for improved ignitability and increased fuel combustion. Simply stated ... Higher Performance.

The U-Groove of the ground electrode results in less flame dissipation. It gives the flame a groove to grow in, creating a larger flame front for a more complete combustion even in the case of lean air-fuel mixture. Effectively, it produces greater firing energy. On the other hand, conventional plugs squash the flame. This is called "quenching effect" and leads to spark plug misfire and rough idle. This has a negative effect on the spark. With the U-groove ground electrode firing can be greatly improved without increasing the spark gap

ACCEL's U-Groove ground electrode produces a larger spark nucleus which stimulates faster combustion, producing more power for higher RPM's of longer duration. The end result is an increase in performance with improved throttle response and due to a more complete burn, greater fuel efficiency and reduced emissions
