    Any bad experience with throttle body bypass mod?

    I bought the inexpensive throttle body bypass kit. I want to do the mod, but I want to make sure I am not creating any issues that might arise from the mod. What is ever ones take on this. Have you done the mod and did it cause any problems? Thanks.

    Never heard of any problems with it, youre basically removing heat sleek from the throttle body

    I only drive it when it is nice out. I drive an 06 Silverado 2500 HD for work. My question is, why does it go through the throttle body in the first place. I know there are a lot mods out there that people do. I am not confident that some of the alterations being made are actually not in some way hurting our cars. So I just want to be educated in the mod or upgrade before I do them.

    you should be good to go on this one. pretty basic and just one of those small things you can do. it was designed as kind of a "de-icer" in freezing conditions, but i believe also was intended to get the motor up to operating temperatures as well. have done countless numbers of them and never (knock on wood) had an issue

    To keep ice from forming in the TB in harsh weather/climates. Pretty sure GM just did it with most (if not all) of their vehicles. For that matter, I believe most manufacturers do it.

    if I remember correctly it was to get coolant running through it to heat the air coming into the engine for cars in colder climates.

    For future reference, ask these questions and research BEFORE you buy

    No issues, but really no noticeable difference. I read somewhere someone used a temp gun on the TB before and after and it was a good 40* swing IIRC.

    They sell a kit for this?

    I bought the parts for the auto store for $6.

    I got the kit for a birthday present. I researched it before I asked for it, but it was info from places that sold the kit. Asking you guys finished my research. Again got it as a present.

    just running a 5/16 hose is cheaper than buying a bypass kit

    The kit doesn't include any hose. It is just a hose adapter two screw clamps and plugs for throttle body.

    I see what you are saying. That would look a lot cleaner. One size hose will work even though it has a different size hose for both attachments? The kit would probably be good for those who want to run it back through the throttle body during the winter. If someone was concerned with that.
