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
What does BR7HS-10 mean:
- B = Ø14mm base (to be tightened with 20.8mm key) - R = With 5 kOhm resistance - 7 = hot thermal index - H = thread length 12.70mm (short base) - S = Central copper electrode - 10 = Electrode gap 1.00mm
Candle BPR5ES from NGK. It is a solid candle of quality, perfect for winter thanks to its hot temperature index, it offers a better spark thanks to its prominent insulation.
BR6 HIX spark plug: the benchmark in terms of performance and lifespan Ideal for high performance engines which do not rev up too much or in very cold cold weather!
NGK BPR6ES candle. It is a solid quality candle, perfect for winter thanks to its warm temperature index, and offers better spark thanks to its prominent insulation.
