  • Using the high heat resistance of the iridium, the spark position is extended 0.4 mm compared to standard types (1.6 → 2.0 mm)
  • Harnessing the low required voltage of the 0.4 mm dia. iridium, the spark gap is wider than in normal types (0.7 → 0.8 mm). Ignitability is greatly increased.
IUF-A series
  • φ10 mm ×L12.7 mm length short type.
  • Ideal for Gorilla/ Monkey Racing.
  • The ground electrode has a slant shape, reducing the thermal stress on it.
