From the factory, coolant flows through the lower portion of the throttle body to (supposedly) prevent icing in colder conditions. Once warm however, the hot coolant heats the incoming air charge. Bypassing the throttle body cools the intake charge, resulting in a few extra horsepower. It's good for up to 5HP, and it's free/cheap.

shbox has a how to. it is very simple and anyone here that has done it can walk you through it. dont buy the ebay TB bypass kit for 15 bucks. go get the stuff at a hardware store or if you want i have kits here that i will give you for the price of shipping.

As noted in a post above, it was put there to prevent "throttle body icing", which might interfere with the movement of the blades. But there are many who have driven our cars in 0*F weather with no problems. Mines been bypassed for at least 13 years.

On the 95-97 engines, you pull the 90* hose off the passenger side throttle body connection, and discard it. You pull the hose off the driver's side connection, and pull it over and connect it to the same metal tube (from the rear of the heads) that the passenger side hose used to connect to. Use a small clamp. Shoebox's website is the best source for info like this:

Generally a good idea to drop the coolant level before removing the hoses, to prevent spilling coolant on the Optispark distributor. Pack rags around the Opti to play is safe. And when you are done, you will need to follow the procedure for eliminating air from the system (courtesy of Shoebox - read the "refill" portion):
