    anybody ever done this?
    On the bottom side of your throttle body, there are two hoses. These hoses bring hot coolant through your throttle body and like the pads, assist in cold weather startup. Do you realize how much better your truck runs when it's cold, (temp gauge at or below 160)? When it gets warmed up, (gauge at 205-210), throttle resonse is greatly reduced. This mod wiil let you have that throttle response all the time.This mod DOES COST YOU ABOUT TEN DOLLARS. All you need is a 12" piece of steel brakeline, (I forget the size, but I remember it was two from the smallest this Auto Zone had.I've got the tag somewhere, though. If you need to know, just send me a message!!!), and two clamps that fit on those hoses (less than 1" diameter). Get the screw kind.
    what exactly do you do?

    It's all in your head. First of all, it costs about $3 to do and just go to home depot and get a brass plumbing coupler(something like 7/16") and use it to connect each side together.

    Second, your truck shouldn't run better before it hits operating temperature unless there's something wrong with it. Generally, the computer will add fuel at lower coolant temperatures until it reaches operating temperature.

    The hose coming from the rad will reach the block you don't even need a coupler.

    All the TB coolant thing does is reduce intake icing that can happen. If it was a lot bigger it could warm your intake air, potentially trading off a tiny amount of performance for some fuel economy, but it's only large enough to prevent ice buildup.

    Only thing this mod does is make it easier to remove your TB for cleaning annually.

    Which you should be doing.

    Annually.

    17 HP and 19 FT. LBS. of torque. Sorry bro but thats in the neighborhood of an aftermarket performance intake or a set of headers. I don't think so. And those numbers came from the before and after dino runs(several hundred $) that you did for a $3 mod. I'm calling bullshit on this one.
