Long base candle NGK BR10 ECM (very cold index)

The BR10ECS candle is a very specific model used on certain motorcycles and even snowmobiles! Its difference with a BR10 ES is simply the shape of the machined well (oblique mass electrode).

They are also used by some to reduce the compression ratio for running in and for motorcycles which requires more room volume on certain routes. With its machined well it is truly specific. It can work well on certain engines. Unlike the B10ES it is equipped with a resistor. It must therefore be put with a resistive anti-parasite 5kΩ.

This long base candle has a shorter porcelain, so prefer to use a shorter suppressor!
