Did anyone's 4bt come with a stock grid heater? I took the VP from Cummins off-road engineering for a ride the other week and he was looking at my engine. He said that the spacer on my intake is where a grid heater usually goes and he was surprised mine didn't have one. I do have the stock block heater.
Anyone running a grid at all? Wondering if it's something I should invest in. Its getting colder and my Jeep doesn't fit in the garage. Will the block heater be enough?
