Review on NGK U5174 48980 Pencil Ignition by Osoulo Sharp

These were replaced on the 2009 2.4 liter 4 cylinder Honda Accord in place of the original Denso used on this Accord. Anyway eliminated the sluggishness (the spark plugs were changed to Bosch, but that alone wasn't a complete solution) and restored full power. Denso showed brownish deterioration as did some older spark plugs. NGK is imo's best product. I recommend spending the money when you've clocked 150,000 miles. The car drives like new.
