Pod Filter vs standard air box?

[BOOMAU]

Hey guys,

question.......

I have had a K&N pod filter setup since I have had the car, and a friend mentioned that the standard air box seems to work better than the pod setup.

Is this true?

If so, I have just installed my standard air box with a new K&N air filter for it and it seems to be a bit more restrictive. Boost does not seem to come on as high as it used to and when "blipping" the engine to about 2k rpm the revs seem to drop alot lower (drop to just under 500rpm)than when I have the pod on, the revs then seem to creep back after a few secs. The pod never seem to lose revs. Obviously there is a noise difference aswell.

What do you guys think?

Anyone tested the pod vs the standard air box at all?

Could it be that the car was used to a certain air flow which has now changed?

Which is better?

thanks.

As for testing the difference, I'm sure you'd find a few threads that cover this. Anyway, I'll answer your question.

The pod filter is probably going to be better for flow and total surface area.

The panel filter is better as it restricts heat from engine bay entering.

What you need to do is make a shielded area for your pod filter that seals (for the most part anyway) when the bonnet closes thus creating a sanction where hot air cannot enter. This gives you the best of both worlds.

People usually use aluminium as it is easily cut and shaped. Then use sticky heat shield tape to keep the heat out.

I actually relocated my filter down to where the stock intercooler goes. Seeing as though mine is no longer there. The only problems I have is filter changes are much more often. and when you drive through a puddle during rain it sometimes makes the car stall coz you suck up water. I made a quick release for it so I could return it to its natural position during rain and move it back again for more power. Kinda a pain in the arse but that's what I get for owning a sh1tbox

Hey Boomau

Those K&N flat panel filters are just the pits - man I lost 56KWs by changing my Pod filter back to the panel filter.

By the way - all the bits are on the floor in front of the bench?????

You obviously changed more than just the pod to lose 56kw.

I changed from a HKS Pod (unshielded) to the std airbox with K&N Panel filter. From memory the car felt a little more responsive downlow but it's been about 18mths now so I can't be so sure. I don't get any hassles from cops (after being hassled by a defect which is why I changed in the firstplace) and i'm guaranteed clean cold airflow because of the std air scoop. I also didn't like the "whoosh" of the HKS Pod.

My car is making damn good power (for my mods) so obviously the K&N Panel isn't holding my engine power back otherwise I would have swapped back by now.

Why spend $200+ on a Pod and then modify your engine bay just to fit it when a K&N Panel filter costs ~$100 and takes not even 1min to fit without any modifications at all ??

read that topic - everyhitng you want to know will be there

and BazR33 - i doubt you lost thast much power - I have seen dyno sheets to back-up that if a POD is not enclosed in a partition/CAI Box you will LOSE power - but using a POD in CAI and a High flow K&N panel in the stock air box you would't lose 53KW's

After reading the whole post, it seems that there is no real difference either way. For a gain of 10kw to set up a pod, and a box sounds like it is not really worth it. Although seems as tho the air box is a bit restrictive at high rpm.

Still doesn't answer the question of my revs dropping since I installed the standard air box though.

I think that I am going to revert back to my pod which was sectioned off, may look at adding a pipe from the lower front spoiler up to the pod for more cool air.

Thanks guys.

just keep in mind about the water issues when running pipe form down low - good luck
