ACCEL - C-CUT SPARK PLUGS

Accel’s C-Cut Spark Plugs were designed to allow spark to expand directly above the midpoint of the electrode core. This creates a larger flame for a more efficient burn, resulting in better throttle response, high RPM power and increased fuel efficiency. Accel has over four decades of designing and manufacturing race-winning fuel and ignition systems.

  • Spark expands directly above electrode’s mid-point
  • Spark radius is larger but gap remains the same
  • C-Cut design prevents overheating of electrode and misfiring and rough idle
  • Better throttle response, fuel efficiency and high RPM power
  • Larger flame for more efficient burn

Rating: (see review/s)

"I replaced 4 original spark plugs with E3s. Car ran well for 57 miles then picked up a misfire. I checked everything but the spark plugs trying to figure out what was wrong. I had changed plug wires and coil pack at the same time. After exhausting all else I pulled the brand new plugs only to discover the #4 plug was not firing properly. Replaced it and the car is fine. All plugs will be replaced now! I have never had a brand new plug short out in my 45 years of working on my own cars." posted by: Jim on October 3, 2011

"dont recommend in a 1999 chevy cavalier 2.4 l. they make the engine misfire. had to change back to the good old double platinum and the misfires stopped." posted by: on January 22, 2011 view all 5 reviews
