NGK BPM7A Spark Plug
Couldn't load pickup availability
The NGK BPM7A spark plug is a reliable solution for small engines and applications that call for a simple yet solid component. With an M14 × 1.25 mm thread, a 9.5 mm thread length, 19 mm hex and a standard gap of approx. 0.70 mm, it is compatible with many vintage kart engines.
Thanks to its nickel centre electrode and washer seat (gasket seat), it ensures good heat transfer and stable combustion. It has no built-in resistor, so it is important to use it with suitable caps to minimise any interference.
