Sparks Overland Recirculating System

Sparks Overland Recirculating Air System
 
The Sparks Overland Recirculating Air System pulls warm air from inside your living space back into the heater intake, reducing engine strain and improving fuel efficiency by pre-warming combustion air.
 
Designed for extended stays and extreme cold, this system helps your heater run more efficiently, more reliably, and for longer periods when conditions are toughest.
 
Ideal for:
• Cold-weather camping
• Long off-grid trips
• Reducing fuel consumption
• Improving heater longevity
 
PLEASE NOTE : It takes around 2 hours of run time for silicone smell to dissipate.
