Projected Tip, Non-Resistor, 5/8 in. Wrench, Set of
4.
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 cleaner
combustion.
Features:
* Hotter 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
