    Absolutely one of the best products you can buy for your stang! I bought one for my 05' and have had zero problems with it. Yes it's expensive, but in my opinion, worth every penny. The problem with the plastic housing is that they sonic weld the main body together. What normally happens is that weld comes apart after a few or many hot/cold cycles and allows the coolant to leak under pressure. Save yourself some worry and get the metal housing.

    Chiming in quite late on this one but hey... info is good to have. My original plastic housing lasted 7.5 years and 150K miles. The first "upgraded" unit I replaced it with... less than 12K miles and failed in under a year. Living in Flawduh with the heat we have here I decided not to play games and procured the aluminum housing. It's pretty much THE solution to the problem. In fact... once you replace it... you never think of housing leaks again. EVAR.
