GMC K2500 Spark Plug, Accel C-Cut Spark Plug - Direct Fit

Best Seller
$12.87 $15.19 You Save $2.32 (15%)
Add to Cart
Availability: In Stock
Only from APW Rewards

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
