Why taking apart my 3.0 motor i bought from mark nunnaly i have discovered a few mods on it which some of significance and some questionable but this is by far the coolest/wierdest and maybe the most useless thing i have seen and is not sure if they work. wondering if anybody has seen anything like this. They dont seem to be homemade but if they were they are extreamly good quality cause the welds are about perfect, and the end of them are flared. anyway here are the pics.





Every horn is facing in the direction of the throttle body.

Mine has them also Zach, there stock and are used to help funnel air to the secondaires.

Those are factory pieces that help tune your runners. Most people leave them in unless they are making some intake changes that require their removal.

thats wierd cause i have disassembled 4-5 intakes and none of them had these. do they even make a difference?

 

[STL. SHO]

I was wondering also what are the gains/loses to taking them out of a stock motor.

 

[zach44102]

Are there any years that didnt come with those? this motor came out of a 91 plus.

If there were ever a time to use the search button, this IS it.

the threads already going now.... why stop?

I think they cut down air turbulance in the tanks to direct more air to the secondaires, but i'm not expert Zach.

To **** with the search button, more fun to "talk".

Because this has been extensively covered to the point where people were looking at making larger bore horns to work with BBB's.

No, all had them.

Yamaha engineers felt that they made a difference. I believe they effectively raise the velocity of the air flow by extending the runner length as well as inducing a better laminar flow.

 

[zach44102]

Should i keep them with a ported intake and bbb?

 

[Northwestvoodoo]

This is where it gets sticky, some run with, some run without. You can read about all the controversy in previous threads.

Stock intake = keep the horns.
Ported/BBB intake = throw in the trash.

 

[whiteguy3]

I can't believe this was a post. But It's stock. C'mon.

No need to use them with a ported intake and BBB's. End of discussion.

It's about at the same level as removing the saxocone/silencer for performance reasons.

It's strange though, if they're so minor, why install them in the first place? You'd think Ford would want to save the dollar or two per car these undoubtedly cost to manufacture and install.

 

[SHOZ123]

They make the runner longer.

Dude, lol.
