NGK BR7HS-10 short base spark plug (hot index)

NGK's BR7HS-10 spark plug is a very solid, original type short-base spark plug. Use it during your break-in and your adjustments, hot enough, it has the right temperature to make the adjustments and break-in or to run your original engine all the time or even pushed (kite). It is not made for extreme performance. This model R has a 5 kOhm resistor for regulation and protection, it will therefore be accompanied by a 5 kOhm resistive interference suppressor.

-Reserved for engines: origin a moderately powerful or very equipped during the break-in / adjustment period
