I have been looking at a water to air system for the TD4.2 Dx 06 coil cab as it is fitted with the standard factory gear, the factory gear is ok in winter but suffers when towing up this way in summer. I have fitted a mandrel bent 3' exhaust to assist.
I'm leaning toward the Plazmaman unit with their manifold for a few reason, reduced EGT temp, build quality and being Australian made has anyone fitted one of these units?

Cheers.
