TensorRace air filter module / Tensor Technology by Stealth Development for the series airbox with Pronoy fabric.
 
 
 
In comparison to the series air filter and other well-known filter manufacturers, we were able to achieve an increase in performance of up to 7.5 kW (10.2 hp).
 
Stealth Development developed this technology on the "air filter" market and we were allowed to accompany the development of the TensorRace air filter module with Pronoy© fabric with our PR12 right from the start.
 
 
 
The Tensor deflector filter has a special hexagon structure with 70 micron material thickness for a drag coefficient close to 0.
 
Engineered for maximum ram air efficiency.
 
 
 
The series filter has an outflow speed of approx. 20 km/h at a flow rate of 90 km/h.
 
With the TensorRace module, the outflow speed is 89 km/h.
 
Therefore, there is no throttling as with other sports air filters and a better degree of filling is achieved at high speeds with RamAir systems, without "HotSpot" nests.
 
 
 
In various practical tests on the race track with different models, all drivers were able to confirm: "Much better throttle response, more aggressive acceleration out of the corner apex."
 
Suspended and fine particles are not taken into account in the filter work.
 
As an option for road racing in environments with high levels of dust, we also offer an SDX pre-filter.
