does the 05 4.8 thermostat include the waterneck or is it just a plain thermostat???? i have heard and read that 99-03 include the neck, which make it like $50 and 04-up dont, which would make them like $5-$15?!! am i right or wrong

 

Ive seen them for $19.95 on summit's site, it was a hypertech. and yes 04-up just thermostat

 

This is what I am going to do to mine. Drill 2 1/8th holes in it and turn the fans on thru my software. Should keep her cool. Shouldnt be a prob did it in my vette and no probs.

FYI. Don't change to a 160* T-stat unless you have forced induction. The 160* t-stat net me no gains and took away 1 mpg on average.
If you just have to change out your t-stat (there are no gains by doing this) at minimum use a 180* stat. Trust me, you will get worse gas mileage.
