Review on NGK (6737) PZFR5Q-11 Laser Platinum Spark Plug: Long-lasting Performance in a Pack of 1 by Elijah Balzarini

Two spark plugs were not properly packaged. One of the plugs came without a cap to prevent the gap from closing up, while the other ruptured during shipping and was loose in the packaging and may have altered the gap. You shouldn't change the spacing on this type of fork, but I may have to if the spacing is wrong. Photo: The box on the right was not sealed, but the box on the left was. The replacement spark plug on the left was missing the cap next to the spark plug on the right.
