I'm looking to hook up one of these babies to the iX, as it will hopefully make for better cold morning startups!
I see that it is to be installed in the lower radiator hose, but they
come in different sizes. Does anyone know off hand for the e30,
if the hose is 1.5, 1.75 or 2 inches?
Anyone install an engine heater on their BMW have some experience to share?
