Throttle body bypass

[GKrenn]

Is the throttle body coolant bypass mod worth while? What are the drawbacks in colder weather? Anyone done this?

It is worth while as it costs nothing and in conjunction with other mods can add power .

I noticed a slight increase in drivability on my C4. I did not buy a kit, i just cut and re-routed the line. (See picture on my website)
