ok, it's been documented that the EF airbox lid has a significantly better flow than the AU lid (18% better if I remember correctly). What I'm curious about is the rest of the piping from the airbox to the engine. The EF has a split intake system while the AU has the single intate that has a rather unpleasent right angle bend in it half way. To me the EF looks to be a more efficient system however gut feeling really isnt something to go on for changing it. Has anyone got any idea if the EF sytem is a better intake for air flow and also if it fits?
People have said that the EF piping from the TB flows better, however I don't like how it hangs right above the exaust.
I just fit an AU setup to my XH (previously EF setup) though I kept the EF air box lid.
So what I have now is the AU platic elbow straight from TB, the AU flexible piece, then a custom made 3" pipe to meet the EF air box lid.
I'll take a pic of it today sometime and post it.
I believe that is about as good as you'll get on any I6 with a BBM.

What's that?..... Did I hear you say TQE power?
A couple of pics.....
I doubt a complete mandrel bent piece from TB to air box will flow much better, and this looks oh so standard.

I have tried something very similar on mine already, in fact it was almost identical (thanks to AU1SIXA for the lone of the EF cover and 3" pipe) and found it made no difference at all on mine. I really think the flexi piece that does the 90 degree turn has got to be upsetting the airflow in some way.
Maybe I'm clutching at straws now. Dunno, just frustrated with my car at the moment.
If you have a similar setup it won't be holding you back. My engine is producing somewhere around 220kw and this setup isn't restricting mine at all.
(Neither was the EF setup, but I prefer the neatness of this current setup).
What's your fuel economy like?
Rick.

Fuel economy is absolute crap at the moment. I'm luck to get 430kms out of a tank of 98 PULP.
I have even gone and reset the computer just the other night in a desperate attempt to solve some of the issues. Not to mention a Dyno booking on March 21st....unless it gets the better of me and I go earlier!
As you can tell, I'm about to fill the car full of fuel and light a match.
Perhaps you should just take it to Ford and ask them to diagnose it.
