Throttle Body Bypass Kit?
In many vehicles, a hot coolant line flows to and from the vehicle's throttle body. After driving for awhile, the coolant in this line will reach temperatures of up to 230 degrees F!! This hot coolant running through the throttle body quickly heats up the air that passes through it and greatly hinders performance.
By directing this hot coolant around the throttle body instead of through it, it keeps the intake cooler and thus the air flowing through it cooler as well. Cool air is denser, and burns better and more efficiently than warm air.

This is a huge mod in the V6 Z24 cavalier world, while yes it does bring in hot temps, switching DOESNT make one bit of difference. I did it not because I thought it would but to prove to a buddy that it doesnt do a damn thing and I was correct. For the most part everybody that says they have a CAI really dont, unless they are pulling air from a cowl induction of some sort, "Ram Air" or pulling the air from under neath the car lower to the ground and even then it wouldnt cause the air to raise up but a few degrees as it passes by so quickly. Not to mention I went to a college that has a HUGE automotive engeneering program linked directly to GM and they proved this as well!99 K1500 Suburban LT "THE BEAST"

you can do it if you want not going to make a difference, and if you live in a cold state you run the risk of a frozen throttle plate

Like Z71 Guy pointed out I think the biggest difference you'd notice would be in an area with cold temperatures where you might get problems from freezing throttle body parts.
Even with the bypass the throttle body is still attached to the engine at a few points and will heat up some. Air passes through so quickly it would have very little time to heat up.

I almost did this the other day but only because I had a leak that I was trying to jerry rig. stopped myself and just did it the right way it looks cleaner and doing it doesnt give you any performace gain.2000 Silverado Z71 Whipple Supercharger, JBA Headers,3" cat back Flowmaster Exhaust, Volant cai, Pioneer Preimer deck,Orion subwoofer,03 signal light mirrors,03 taililghts
