The new B7 OXD has been developed to optimize gas dynamics in .21 (3.5cc) 2-stroke off-road competition engines.
 
The parabolic conical geometry of the manifold is designed to:
• Improve flow velocity at low revs
• Increase useful return pressure
• Make power delivery more progressive and linear
• Optimize corner exit response
 
Results on the track
✔ Increased low-end torque
✔ Improved traction in technical sections
✔ More controllable power delivery on low-grip surfaces
✔ Over 30 seconds of fuel consumption reduction
 
OXD surface treatment results in:
• Hardening of the material
• Greater resistance to temperature and vibrations
• Improved stability of resonance characteristics over time
• Simplified external cleaning
