intake & air filters

[qmjona]

For the last few weeks I have been running a pod type filter.

I can definitely notice a little more power and it sounds great (was also getting extra 30-50km per tank).

But . . . call me soft but I am a little worried about the fact that they are not legal etc. anyway, looking for other options I have taken out the resonator and put the std filter in with air drawn in directly from below the air box (instead of through the resonator assy)

Took it for a drive, not sure from driving if it feels any better than std. I think it does but hard to say. Certainly I've lost that nice intake roar at full throttle, which tells me that it is the standard paper air filter that cuts out 90% of the intake noise not the resonator.



Anyway this has left me with a couple of questions.



* is there an aftermarket high-flow re-usable type filter available to fit in the standard air-box? something like K&N or rush? (+where to buy?) would the nice noise I had with the pod return with a performance filter in the original air box?



* I now have a clear path from the bottom of the airbox to the front left hole in the front bumper, only about 1m, I could easily put some flexible ducting in. Intake at bottom of the airbox is 75mm, would catching 75mm of air through the bumper inlet be would it be worth it? would it create any significant positive pressure before the filter? I'm tempted to do this if I can get a decent filter, because I can definitely notice just from driving on a cool day that the euro pulls harder breathing cold air.



Appreciate comments from anyone who knows about this or has tried something similar.

ITG make excellent filters look at www.fuelsaver.com.au. I had one of their POD filters on my Corolla Sportivo and Compared to the K&N Xtream Top filter they also have Panel filters..no comparison. You could buy an Comptech Icebox if you want to maintain the lower part of your existing Filter setup I paid $236 delivered to Australia (depends on the exchange rate though) details are at www.comptech.com. I bought my Comptech stuff from http://stores.ebay.com/Acura-of-Escondido-Parts they are very resonable and he is very quick to ship.

A proper CAI like Injen or K&N Typhoon is way better than the Icebox or a home made pod.

I just don't get the whole DIY scene for intakes - you can get the K&N or Injen for around $300. Well worth the money.

That may be true but the good thing about the Comptech is that is very Subtle which I like personally... but each to their own thats the good thing about choice.. :)

I've thought about getting the Icebox. The advantage is stock looks and no hydrolock risk. The downside is some people report no noticeable gains. how are you finding it?

[qmjona]

Its not really diy, just looking to know what aftermarket filter replacment options exist.
OK adding intake pipe is, but this would be very easy.

As for the legalities of it... IF I remember clearly from my dying memory...The EPA states the the filter cannot be oiled, so technically it makes the K&N ones illegal.. Filters are to be enclosed if it's in the engine bay. So if you are running a CAI, technically it's legal because it's away from the engine bay.. But then again, different cops have different knowledge....

I will let you know when I get the car.

there is an article comparing some of the more popular intakes (i think it is US brand only)

VARIOUS INTAKES COMPARED- THE ARTICLES (http://www.tprmag.com/issue/1/1_intakes.shtml)

THE RESULTS (http://www.tprmag.com/issue/1/sr-results.shtml)

have a read at all the articles.. and how the dyno was conducted... hope it is helpful :D

[egSi]

K+N panel filter owns IMO :thumbsup:

[razaman]

Can anyone tell me why it's illegal to have an aftermarket intake/filter? What is the reasoning etc

It's almost laughable - I'm not going to laught because our gov't is stupid enough to start doing the same, they're on a stupid roll at the moment.

I beleive from what I have been the POD filters are illegal unless enclosed from an EPA prospective as they can drop oil on the road.

K&N panel filter for original air box $125.
Think I'll go this way.

Thanks for posting this :wave:

The problem is you are fitting it to a new car so how will you know if it is any different? :( Hmmm - you've got me thinking about this Icebox now. Less attention from the LAPD, zero hydrolock risk, looks stock from the engine bay.

Less attention from the LAPD, zero hydrolock risk, looks stock from the engine bay. If you have got the money, go the wank factor and get the mugen carbon fiber air box. It looks much better than the comptech one!

Or you could just go short ram and put a cover panel over the top of the filter.

This is similar to the injen intake thread running, but I'll post it here because it relates to what I was asking above.



I have taken off the pod filter off, put the standard filter back in and hooked up a 90mm cold air intake from the bottom of the airbox to the opening in the front of the bumper under the headlight. With mesh in front to protect it from anything larger entering.



What is interesting is that using very rough 0-100 timing to compare the 2 set-ups I have observed that although the POD sounded great and so 'felt' faster, I can get about 0.2 - 0.4 second quicker 0-100 time with the standard filter with the cold air intake.



Although the timing is rough (stopwatch while driving - an auto) I believe it is valid for comparison, so what this tells me is that the benefits of a high flow pod filter are far less that catching cold air from outside the engine bay.



Perhaps this supports something that i had previously wondered about the set-up of a high flow filter in the engine bay, that is what do people callit a 'short ram' set up? - there is no RAM effect, and why do some people call it a CAI? there is nothing cold about drawing air from the engine bay - which is actually very hot in the euro.



Anyway, this is what I have observed. By the way I didn’t do it to save $, I wanted to directly draw fresh air, something that the CAI kits I have seen don't do (although drawing from the space behind the bumper is probably the next best thing)



I still have to get the K&N panel filter which should work well with this setup.

i have send a email ask RTA about tat already...
they said......
The fitment of an aftermarket intake system will need to be engineer certified to show continued compliance with the Australian Design Rules.
http://www.rta.nsw.gov.au/registration/downloads/vsi/vsi15.pdf

so... is ok to install tat if you got the engineer certified.

Whats the K&N part number?

[qmjona]

K&N US part no. is

If you have got the money, go the wank factor and get the mugen carbon fiber air box. It looks much better than the comptech one!

Wank Factor????
I have the Mugen box installed, hope u not referring to people who use Mugen parts as wankers! just kidding :p ... anywayz the gain is not great but Quality mate, u cant go wrong with Mugen....

[euro77]

geez.. how much does the mugen carbon fibre air box costs you?
(if you don't mind me asking of course)

[stephen8512]

anybody know anyone selling the INJEN CAI here in aus? i found some on ebay from the US but if i can get it here, id much rather get it here than the hassle of shipping, etc etc

[Gibbo]

can you advise us of the cost for the mugen air box - looks sweet !!!

[LOC888]

How does the grouppeM compare to mugen?
