In the car they can be pryed out with a hooked prybar, very little effort is required.
I take it the cooling system has to be drained since the freeze plugs come out?As stated above this can be done in the car with the intake removed. I used a chisel and a small pair of channel locks and had it done easily. Thanks again MMR for a quality product.
Yes I already had the coolant drained due to having to remove the radiator for the charger install.
Do you have before and after data logs of temps?
I would like to see some data before shelling out money.
