Air Intake

OK I'm looking to put a Pod filter in my car for the induction noise mostly and one day i might upgrade my exhaust.
Im interested in what people have done.
But i'm wondering how this works : http://www.justjap.com/store/product.php?productid=19346&cat=272&page=1
i was looking at this but a little bit pricey and doesn't fit my car i don't think.http://www.ebay.com.au/itm/170757837186?ssPageName=STRK:MEWAX:IT&_trksid=p3984.m1423.l2649
Or something like this tho the air sensor is in the wrong place :/ : http://www.ebay.com.au/itm/200696787783?ssPageName=STRK:MEWAX:IT&_trksid=p3984.m1423.l2649
Help needed
