    re:

    From the factory they route coolant threw a little tube in the bottom of your TB to warm it up. They do this so if the car is driven in cold weather ice will not build up in the TB and cause it to stick. The bypass kit is a tube that connects to the in put tube of the TB coolant line to the out put tube of the TB coolant line. This bypasses the TB and does not allow the TB to warm up, which then does not heat up the in coming air so you will produce more horsepower. Worth the money?? hmm will I'd say its a cheap horsepower mod and I have it and would say get it.

    Also if you do drive the car in cold weather then I'd recommend putting the TB back to stock config for that time, then when summer hits reinstall the bypass.

    ehhhh...useless mod IMO. The air goes in so fast it doesn't have time to heat up, but that's just my theory with nothing to back it up...and dynos vary from pull to pull, so that doesn't help much either. But it's a free mod so why not...I never bothered to do it though

    I have it and I drive that car all year around. I though about removing it this winter but so far I've had no problems. So I would say do it, IMO it was worth a few ponies.

    Well don't pay anyone for a kit... Here is a link to an article that tells you everything you need to know http://www.thirdgen.org/newdesign/te...ntbypass.shtml.

    Is it worth it? Well in now way at all is it able to hinder performance so even if it was a .5% gain I'd say it was worth it.
