AU to EF airbox swap

Has anyone tried swapping the lid of the AU airbox for the EF lid as at http://www.autospeed.com/A_0073/page1.html

Was there any improvement?

Is the AUXR8 and AU2XR8 airbox lid the same?

there is about a 10 -15 cfm improvement because of the pipe inside the lid drawing air from the centre of the box.. as opposed to the au and eb... you dont need to swap the lid though.. just get some pipe about 65mm in diameter and 150mm in length (dont quote me) and shove it in the hole.

Cheers eb_5litre, but I wonder why Ford would change the design of an already good flowing airbox, and make it worse? Or at least not as good

I don't know about AU's but I was shocked to discover that on the EL airbox, not only have they not included the EF style internal extension, but the outlet is significantly smaller than the EF one!! (the plastic airbox top is exactly the same - the smaller outlet is part of the rubber adaptor that's attached to it - the internal extension also forms part of that adaptor).

Ford have done a few odd things with regard to restricting engine breathing on their machines (6 cylinder anyway) - the original ED airbox to throttle body duct also had quite a restriction moulded into it - sort of like a ventury.

A Ford dealership mechanic once told me that the intake restrictions were to make the cars meet an ADR "Acceleration/Brake" test whereby the car is floored off the line for a certain number of seconds then brought to a stop - the stopping distance must be within a certain range. The factors involved are acceleration rate and brake effectiveness, so when confronted with having to meet the requirement of this test the cheapest option is to restrict the engine's intake system. Has anyone else heard of this??

If it's all actually in order to quieten intake noise, all I can say is what a bugger of a way to do it!

Ahhh, maybe it's all to do with keeping performance figures in the correct relationship between 6's and 8's?

Yeah had a chance to look at the difference between the EF and EL intake setups, handy to have an EF and EL living in one house hold :D :D .

The difference in the size of the tube just after the airbox, is 21.5cm diameter for the EL and 28cm for the EF. Quite a significant difference.

This would explain why the EL is perceptably quieter apart from the dizzy cap setup which eliminates the ever ever so slight of beat fire of the EF.

Well i guess from this trait this explains why the later models may feel abit doey when accelerating. Whith slight mods the AU is a much more powerful car than the EF.
A guy i meet at the dyno day had a moded induction system pace maker headers and exhaust thats it, he was getting 122kw at the wheels.
The engine it self i reckon the AU is better and more pwoerful but with these air restrictions there potential seems hidden.

Thumbs up

I just did the modification to my EB and i must say i noticed a definate difference in response.
Got some 80mm tubing from Bunnings and flanged the end.
The chick at the check-out stuffed up and gave me a metre for $2.20... pretty cheap mod if you ask me.

Was this a standard 6 or an XR6?

eb5litre,

Thats definitly the cheapest mod i've heard, good thing you noticed a difference as well. Does the car have better pickup???
Well all you need to do now is get your self a filter, either Uni Filter or the onw i use O2Rush by Finer Filter you defenitly feel the difference.

(\/)ADXF,
Yeah it was a Falcon S, not an Xr6. Thats why it's impressive, even the XR6 boys weren't getting the figures of this car.
But if you do up the XR6 you'll get even more power.
