BlazeCut are the leaders in fire suppression systems.
We supply as 2m or 3m systems. Good peace of mind for your VW, we have these fitted in all of our vehicles, these units are actiated by excessive heat so that the fire is suppressed before you have even stopped the vehicle.
Easy to install either cable tied to the underside of the engine lid or to the roof of the engine bay in a Kombi.
