Coolant flows through the bottom of the throttle body. Take a look. You will see a coolant hose on each side. Take them off and hook them together with a hose coupler and you have then made the coolant bypass the throttle body.

The point of it is to keep the throttle body from freezing. Unless you live in Alaska or Antartica, you don't really need it. Most people claim to fell a difference.

Doing the bypass keeps the intake charge cooler, thus denser, thus more power. As little as that tube is, not much coolant is flowing through there - I don't know if it's worth it. I have no number to back that up, maybe someone else does.

I haven't done it on my truck, but I did do it on my Z. The LT1 has a great deal of coolant flowing through its throttle body.

I did it to my truck didn't feel any extra power but it cant hurt. It defintly kept the TB much much cooler. I live in Florida so freezing isn't a problem. I didn't couple my hose because there is enough ro run from the engine to the radiator.

I did it and it does keep it cooler which is good here in TX. I feel that it may have helped a LITTLE but nothing very big. I guess every little bit helps though. I found these dyno results if you want to check them out.
