I've considered this also, but in the Mid-America catalog its says something about "not recommended for use in below freezing temperatires due to possible throttle body icing". Does this mean if I drive my car in winter time tempertures that I'll have problems?

It causes no problems or damage to the engine. So long as you dont drive in near zero temps. And in FL youll never ever have that problem.
Its a couple to 5hp gain, no more than that though.
All you have to do is disconnect the two hoses leading into and out of the TB and mate them together with a pipe and 2 clamps. Thats it.
In extremely cold weather, and i mean sub-zero or very slow cruising in just-above-zero temps, the coolant is meant to heat up the TB and get the plates hot so they cant freeze. Only problem is that ive never seen or heard of anyone ever having them freeze. Of course, once the engine gets even slightly warm, they cant freeze anyway because the engine transfers the heat quickly.

I forget the site but some F-Body guy dynoed after doing the bypass and there was a 3 or 4 hp gain. Nothing huge, but considering it's free why not :yesnod:

Its not the fact that its only a 3 hp gain but if you keep finding these little 3 hp gains they all add up. ex if you find 10 small hp gain additions to your car then you all of a sudden have a 30 to 40 hp gain. :eek:
Once your engine warms up to temp wouldn't the throttle body be warm enough to keep from icing? I have always thought something like this was only good for temps up in the extreme northern part of the US or Canada but if you live anywhere in the central or southern US then you shouldn't have to worry about this change. I haven't done this yet but I will :smash:
