Is there make any difference?

The pod filter sucks in hot air from the engine bay, which would lead to an increase in the air:fuel ratio (less fuel). However this would also lead to a performance compromise, right?

Am i on the right track? Or is the point of a pod filter nothing more than allowing easier airflow?

Cheers

do a search on pod filter Vs CIA etc. there have been loads of threads on the subject and many arguments both ways

http://forums.justcommodores.com.au...s-air-filter.html?highlight=pod+filter+Vs+CIA

but to cut out all the bull, no matter what you have, unless it has a good source of cold air it ain't gonna do jack

if your gonna fit a POD filter, have a look at my ride (link at bottom) to see how it should be done

ive used the original airbox gutted it and put a k&n pod in it cut the front wall of the box out and used downpipe for a duct that sit's behind the bumper and come's up through
bottom of the airbox
pod's flow better then a panel filter but without cai or a heat shield the just breath hot air and are useless my setup cost $70 including the pod

Still yet to see proven results of a pod over a panel on an NA car.

The issue gets confused because more than one factor is at work:

Low restriction = better economy and more WOT power.

Cold air = worse economy (yep but not because there is "more" fuel) and more WOT power.

Hot air = better economy (at part load - provided detonation is avoided) and less WOT power.

In terms of economy, the PCM will always chase stoichiometry at part load so any effects will be due to factors other than fuel mixture changes. The high load mixtures are extrapolated from the part load (closed loop) mixture requirements..

Cheap 6, can you explain the basis for which you have made your cold air and hot air predictions?

Heres a how to on how to put a pod into the standard air box, but to be honest it is no different than a panel filter in he standard air box:

Is that the one I wrote? (didnt click the link)

You are right, either way the engine itself will only suck in so much air ( I think Abba fan said that once in another thread too) although the pod has potential to allow for more airflow without some sort of force like a charger or a turbo, you will only reach the air intake that the engine can really,a nd a panel filter meets and exceeds this, as does a pod.

Get some other mods on the car before going into advanced air intakes and such is my advice.
