El or later air supply in ed

[TadKa]

would there be any point in installing (excuse the technical terms) air supply bits. on my ed. I'm talking the metal thingies that are different on an el I'm looking at. what is the difference? I'm planning on maybe getting a bigger better air box and intake anyway. just keen to know what the extra bigger bits do? am I making sense?

ok
The metal thingies are the inlet manifold. The EF, EL and AU use what is called a BroadBand manifold (BBM for short). Inside the manifold are 6 butterflies that switch the direction the inlet charge can flow at a set RPM (3800 rpm if you use a factory ECU). The butterflies redirect the inlet charge to take a short or longer route to the cylinder head.

The jury is out on the benifits or upgading, some have had good results others not too sure. I personally have found the car is better mid range, but again I think you have to look at the whole package..

Do a search and you'll find a few threads on the conversion...

Here is one i found really quickly
