I was wondering if anyone has tried using an intake heater off of a tractor? I see them on ebay for around $20. To me, it looks like you could make one work on a 4bt with a little drilling and tapping. I think a person could drill in, at an angle, at the base of the pipe coming over from the turbo side. There is a flat spot that would make this an easy task.
Any ideas? Has anyone tried this and made it work?
