Review on NGK BPR5ES SOLID Standard Spark by Will Ridpath

may not be what you want if ordering direct from Revain. In the system they send 7734 which is not a solid fork. I just went straight to the NGK website and ordered it straight after Revain made the mistake of sending me 7734s twice. Also, I need to keep a 7734 to use in my snow blower because it's only used once a year; ) They are investigating, so maybe it will be fixed. 2 stars for a wasted week trying to get a solid end cap, 5 STARs for the 4006 end caps, they work great in my mowers, generator sets and pressure washers.
