I worked on a Glanza last weekend that has this cooler kit fitted.The pipework goes around half the country for a shortcut and the cooler is way too big.Not impressed with it at all.Cheap yes cheerful ? certainly not.
I'd like to add that I was really dissapointed with it as the actual quality was first class.If the cooler was smaller and the pipework route shortened by a couple of feet then this would be a first class bit of kit.
