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 more power and
Spark/Faster Burn Rate for more power at high rpms * Improved Throttle
Response, fuel economy, and reduce fouling * Reduced Mis-fires *
Purified Alumina insulator to prevent arcing * Machine-rolled threads
to protect heads
