I didn't see one on mini4x4, and I'm not too familiar with Canadian vendors. I know G&R has them in the states, so I would recommend them or importing one direct from Japan yourself.
Thanks Ulterior. - I saw them on G&R, but the shipping (to Canada) was almost $100, so I'm trying to find something more reasonable.
This is what I ran in mine. 195 would have been better for winter. I did drill a small bypass hole like factory thermostat has.
