The best option if your looking to get rid of that steel crossover tube. It's always in the way of your new blower and intercooler lines. Not to mention it does not match the custom underhood look you have spent so much money on. In this setup you get a thermostat housing (thermostat included), and 2 head fittings. Each one has -12 ORB ports as well as 3/8 NPT ports. The driver's side fitting has a -8ORB port with a plug so you can burp the system just like Ford intended. The thermostat housing comes with a Meziere fitting with either a 1 1/2" barb (matches the upper hose), -16 AN, or -20 AN. This housing has the bypass holes built in so no more drilling the thermostat. Also it has a extra 1/2NPT port so you can plumb a extra line (I recomend returning your head cooling mod here).
