I did this and have not had any problems although I park my SS from Nov-April.

it doesn't damage the motor at all. I did the bypass on my old 95 z28, and now on my 00ss. the concern is that driving in cold weather and then sitting might give the potiental chance for the throttle body blade to freeze in either the open or closed position. I lived in KS all 6 years I had that car (and we get ALL 4 SEASONS there) and never once had a problem.

one more thing, it won't give you 6-8 rwhp, you'll get a fraction of that...

I live in Florida...and never bothered with it.

Did it for the hell of it, no problems, no real gains. Just one less thing to worry about when swapping out or taking off TB's...

same here did it for the hell of it ...took 10 minutes......dont believe i saw any gains......and im not concerned since i dont drive my car from november to may anyway.

1-3 is more lik eit if that and I drive all year round in every condition including snow and sub 20 degree weather with no problems for 4 years now.

It would have to get 30-40 below before it would have any negative impact....as for gains...I'd say a couple of RWHP....but well worth it...doesn't take 5 minutes....

thanks for all your replies. I live in n cali, san francisco, so i doubt it will go 30-40 below.

You don't really need a kit though, do you? You can do it without the kit, just go the the hardware store and pick some of that stuff up if you need it.

I just did the mod today actually, and it seems to have "smoothed" the throttle response a little bit. Who knows exact #'s unless you dyno, but Id say its worth 10 minutes and $5-7 at your local hardware store.
All you need is:
1- 5/16 brass barb connector (or plastic, I chose brass for durability)
1 foot of 5/16 gas hose (didnt need all of it though)
3- hose clamps
2- 1/4 vacuum caps
I think I might do a tech post on this free mod seeing as how other pages tell you to "buy the kit offline." The kit's a waste of $. What do you guys think? Should I do one?

NO IT WILL NOT HURT ANYTHING!!!! Unless you live in ALASKA

and drive your car as a winter beater

or have a snowplow mount for the front. It will also make a differance where you live. All the 5.0's have the same shit it is Mostly there to help with emissions by heating throttle body it helps to keeps hc's down and reach a emission friendly operating temp. quicker!!:slapboobies:
I just wanted to use the boobies for something!!!

It ain't worth your time IMO, unless you are just bored.

Or unless you want to make sure your throttle body is always as hot as your coolant!!!!

But let me guess your one of those guys who also thinks a cold-air kit is a waste also.......Why put cold air into a throttle body filled with 220 coolant???????
