When it comes to pod filters it seems that it's about as controversial as asylum seekers in Australia LOL
Just to quote from another thread as to what I've written in the past
In summary pod filters in a half decent box flow more then a factory air box assembly, creating less turbulence along the way.
We can seen as being biased which is COMPLETELY understandable, however people can do the testing themselves. All they need is a coke bottle, clear tube and water, fancy flow benches are not needed for comparative testing as shown in the link below
Modded Factory Air Box Testing
Food for though.
Cheers,

Good grief Soop, I was waiting for you to pull your Googleoligist crap up again! The scary part is people actually believe what your saying based on your technical spray painting back ground………..
If you actually knew what you were talking about, then assuming ideally pipe flow under a best case (never going to happen), an ecotec on idle with the factory sizes pipe work would have a Reynolds number of close to 4000. To say you the trouble of Googleing the answer from a "credible source" it means that turbulent flow it present on idle!
Given that the inlet track on a EFI car is FAR from ideal when it comes to pipe flow, especially under transient response (sharp on off throttle), with vortex shedding etc, accurately measuring mass air flow is ALWAYS going to be tricky from a control systems perspective.
Fortunately the engineers at Delphi (their maf in these cars), incorporate a honeycomb/vane structure, to insure that the mean velocity of the air traveling through the MAF is uniform across the cross section of the MAF.
If the bullshit you mentioned wasn't a problem in the beginning they could have saved themselves probably millions by now for not including they vane in the MAF in the first place, however it is for the reasons I mentioned
On a specific note in regards to pod filters, to say a properly designed pod ensure doesn't work, is definitely selling very short the engineers at Honda and FPV, as they've been used on the Honda S2000 (Bare in mind that for years (if not still) the most powerful production engine per L) and new coyote supercharged V8's. They definitely haven't been used for looks or especially sound, as they're more difficult to keep quite, which is extremely important when it comes down to complying with Australian Standards, so why use them?
Soop, do you know something that the engineers at Honda and FPV don’t, from your vast Googleing expertise?
