NGK BR9EG spark plug with long thread with pull-out terminal, bent electrode

Special racing spark plugs with platinum and iridium electrodes are also available.
They are especially recommended for highly prepared engines and when a rotor is mounted.

The spark is much more stable, especially at high engine speeds. In addition, the thinner electrode is not tarnished, in contrast to ordinary CU electrodes.
For high-end cylinders like the MHR TEAM, Hebo Manston II and the ProRace we recommend NGK spark plugs with a 10 or 10.5 value.
Spark plugs with interference suppression should be used especially when a rev counter is installed, because without these spark plugs the rev counter reacts with speed jumps.
NGK is replacing Platinum by Iridium...
