coolent hose on the throttlebody?

[Rockinlittle325i]

I was wondering why we have these?

I had to delete this to be able to drive again because the gasket sprung a leak

is deleting this a bad thing? or does it really matter? like a heater core or AC?

its to warm up the TB for cold climates...

In charlotte you aren't going to need it. And in warmer climates you don't really want your TB hotter. It just increases your air temp, lowering performance.

That fucking gasket blew on me on my way down to Bimmerfest.

Alot of people told me that had deleted it, so it's not a huge issue.

yup, exactly. I deleted mine, it's just an annoyance.

I was going to delete mine or remake the gasket next weekend, but I'm not sure what I should do.
I live in California, so it's warm here, but I do go to Tahoe almost every weekend in the winter and it's cold there. Is it cold there that I should keep the coolant hose, or should I delete it?

The throttle body heater loop is to prevent the throttle plate from freezing in low temperature environments. If the car will never see those environments, it can be deleted. Otherwise it should be kept functional. Lifting off the accelerator and having nothing happen when the car is at speed leads to more excitement than most wish to experience (been there, done that)!
