I have a 2004 cobra and I was wondering if I should spend the 300+ on an aftermarket throttle body or just port out the stock one....for free.
If the tb is stock there is no point in smoothing it out, the gain would be none, if you are looking for gains a bigger tb would be the way to go!frank07stanggt said:So you wouldn't smooth out the stock one? It's pretty rough. I'm not trying to make the inlet holes bigger just smoother. Would rather save my money for more effective mods at the moment. If its not advise then I will do nothing. I just figured there isn't much point in porting the elbow and blower if the throttle body is still all rough and restrictive.
