Bigger Throttle Body to replace stock??
So I took my '04 f150 5.4 into the dealer on Friday and was told I need a new throttle body. Of course I didn't have them do it because they wanted $660 to replace and reset the PCM. I've had it off and cleaned it recently so it's an easy task. Anyway, so I was looking online at stock throttle bodys and was thinking of maybe getting an aftermarket one. My motor is all stock right now not even a custom exhaust yet. So does a bigger throttle body make any more power or affect mpg in any way? Is it work the extra $$ to get a bigger TB??

From what I understand a throttle body spacer will not give you increased power. It increases air flow, which if you have a stock truck, won't really net you any gains. There are a few threads about this already and a few people say they noticed a small response in throttle. I would just save the money and buy something else for your truck and that's just my 2 cents.

It's not going to help you. However what is wrong with your current throttle body? Also most aftermarket throttle bodies don't come with throttle body motors. So, if yours is bad you have to spend even more, for possibly something that isn't going to help you without ALOT of supporting mods, or a supercharger.
