When we originally developed the under bonnet system we were aware that the restrictions of the original air intake and air outlets into the car did compromise performance a little and in the warmest of climates this system may be less effective because of these restrictions.
We set about designing a unit which would fit inside the car, behind the dashboard and give optimum performance by using recirculated air.
The resulting system maximises the system performance and ensure the car stays cool in the warmest of conditions.
