OH-196, OH-206, OH-207 and OH-281 kits fit a 16mm diameter spline.

HKB Steering Wheel Boss Kits are made in Japan and are double drilled to be compatible with Nardi/Personal and Momo/Sparco/OMP steering wheels.

All HKB Boss Kits are designed to provide plug and play horn operation, indicator self-cancelling, airbag light cancelling, HICAS operation and cruise control functionality, depending on application.

• 6x70 and 6x74 PCD
• 60mm depth
• Airbag compatible

Functions of switches other than the horn on the steering cannot be used. The meshing length of the serrations may be short on some vehicles that bolt the boss. There is no problem if you can tighten the bolts to the specified torque and fix the boss.
