Long base candle NGK Racing BKR8EIX iridium (medium cold index)

The BKR8EIX competition spark plug is a top-of-the-range spark plug specially designed for performance, we recommend it on 2-stroke engines in competition, it is already widely used in motocross, super motard and 2-stroke karting, it has an average cold index for achieve maximum performance with a very well tuned engine. It is an excellent asset to use for racing machines.


The temperature index is 8, its design and materials are quite different from the B8 EVX models. Here the electrode is made of iridium (more upscale than platinum ), which offers extraordinary wear resistance, powerful ignition, iridium has extreme anti-corrosion properties. In long base, it is delivered with olive. This candle has a regulation resistor.

- Base: long
- Temperature index: medium cold
-Resistance: yes (r) to be mounted with antiparasite resistive
-For the engines: very advanced and well tuned.

What does BKR8EIX mean:

-BK: Ø14mm thread (BPC to ISO standards), tightens with a Ø16mm hex key, 1.25mm screw pitch
-R: resistive spark plug
-8: average cold heat index
-E: 19mm long base
-IX: iridium electrode
