When i had the heater box in bits i decided i would get a new uprated heater matrix considering the effort required to remove and refit the box. They have about 30% more elements than the standard so hopefully 30% more heat output. All went together well but getting the box back into position requires a lot of patience.
Once back in and all connected up it was good to feel the heat and the noticeable more air coming through the windscreen vents – but that was mainly due to sorting out the blocked internal passages in the box.
