Short base candle NGK BR7HS (hot index)

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

- Reserved for original engines with moderate power or very equipped during the break-in/adjustment period.
