I have a 2004 f150 supercrew. Everytime I brake when going down hill i get a slight kick back seems like its from the drive shaft? Any one face anything similar?

 

I know this topic is prob beaten to death but whats the best intake for the 5.4s. I need something reliable that wont throw any lean codes. Any help would be appreciated Thanks

 

first the kick back, can't help there but can tell you my F250 feels like your hit in the back by a hammer when wot and shifting. But I think you can look it up I read along time ago that it was a pretty common problem on the 04's. Look it up. There is a cool feature called SEARCH it works sometimes.

Now for the best air intake. you said that the question is probably beaten to death. Knowing that why don't you look it up? Its under exhaust and intakes (I think). Also no one is able to decide which is the best, but we can all give oppinions about good ones and bad ones. You have to decide for yourself and do alittle bit of research.
