Personally, I keep the K&N filter in most of the time, but change over to the paper one (or foam finer filter), when running in convoy or on really dusty tracks.


I was thinking the same thing Brett but not sure what brand of pod filter is a paper construction and where I would get one.

Re: Air intake design & modifications


Kev,

Do you have any pics of your progress so far?? If it all works out, Im interested in getting in touch to see if you can help me do the same with mine.

Im not intending to go off road at all so can i get away with not using the bypass valve setup and just go for a simple pod filter setup straight off the MAF??

Jalal,

Do you have any pics of yours that show the full length of the CAI?? The pic on cosmo doesnt show where your piping ends up....

The bypass valve is your security not only for off-roading, but it will also protect you against ingesting water by crossing puddles on the street as a result of heavy rain (depending on where you are) and you can drive around much safer with it there. It's a small price to pay for such a huge peace of mind.

Hi woody,
Here are pics of the CAI so far.
All I need to do is get a pod filter and cut the down pipe length into the wheel well.

Converting it into a short-ram for off-roading will be as simple as undoing two clamps and removing the straight section and 45 degree bend then mounting the off-road pod filter directly onto the MAF adapter.

Re: Air intake design & modifications


Kev and all,

This is just a word of warning to anyone thinking of using the short ram pod filter set-up in their engine bay in NSW:

I am quoting this directly from a NSW police-officer

quote:


Hi Guys,

I work as a cop in NSW so I can give an insight on the legalities but only obviously for NSW.

Pod filters are illegal unless you have an enclosure. Further, blow offs can't vent into the atmosphere.. Basically if you have a engineer's certificate you are generally fine, but from my experiences most ppl never do especially with the tachos on the 'A' pillar.



Further to the above, any cold air intake set-up in the car MUST be supported, meaning it must have supporting brackets to the body of the car inside the engine bay.

This ruling applies to NSW and some other states, so you better check on the legalities of what you're about to do before getting in trouble at registration time or random street inspection.

I am sure I have read this ruling in an ADR somewhere as well. It does not apply to filters that are located outside of the engine bay however (the enclosure requirement that is).

Re: Air intake design & modifications


All noted Jalal, so I would like to make the following clarifications.

1) Brackets will be fitted but have not been fitted yet. Woody wanted a progress pic to see how far I had come with my design.

2) The short-ram pod will only be used off-road, otherwise the K&N pod with dry cover will reside in the wheel well as it does with the Cosmo CAI design.

Also, some side notes...

3) When Brett posted his SRI your comment was only
quote:

jalalski wrote:
Do we now call your exy, Lifted, Loaded and Roaring? emoticon

To clean the air filter box, just drop by your local mechanic shop and use his high pressure air hose to push the bugs and dirt all out instead of trying to vacuum the box.



4) When Roman posted his SRI setup here you did not comment at all.

5) When Matt posted his SRI install here your question regarding enclosing the pod was mainly directed towards preventing heat-soak.

Apart from your current reference, the only other mention of pod filters having to be enclosed was back on page 13 of this thread when Matt mentioned that pod filters were illegal in NSW your comment was
quote:

jalalski wrote:
quote:

remember also that in NSW it is illegal to have a pod filter, rta states that air filters need to be in an air box


Not entirely correct. The RTA states that pod filters need to be secure and enclosed to ensure you don't loose them on the road while in action. The way the filter is located in the CAI set-up in our case, is indeed enclosed and secured. Even if it falls off the pipe for one reason or another, it'll be trapped within the splash guard enclosure in the fender. It won't go anywhere.

The second RTA/ADR requirement is noise levels and am pretty sure that a pod/short ram set-up is louder than the CAI one. (someone can correct me if am wrong)



So why does it now sound as though you are being a bit more "critical" of other CAI / SRI designs ?

Re: Air intake design & modifications


Hey Kev,
did you make your own MAF adaptor, buy a QR25 one, or modify another style? This looks like what I have been considering.
Looks good
 emoticon

Edit...Since had a closer look at your pics sorry mate! Silicone/ rubber piping (available from auto parts stockists) with formed bends what you used? I was gunna use the temp rated "off-the-shelf" aluminium inter cooler pipes for the straight run, and possibly colour match it to the engine bay, along with the blue silicone bends and couplers.
I know there are "generic" Nissan MAF adaptors available as well but was concerned on the quality.
Cheers

Re: Air intake design & modifications


Sorry Kev if you took my general comments as being too personal and took offense, I was making a general point about the legality of the short ram set-up if not for your own benefit, it was made for the benefit of other members who may think of using a short ram CAI.

As you have done your homework and went and dug-up all of my previous posts, you can clearly see it wasn't the first time I said this, so a reminder was due seeing that more members are contemplating this mod and may consider using the short ram set-up on permanent basis. Also the fact that some members are not reading the previous 40 pages of this thread (like you are)

I had a chat to Noel last night and I predicted your reaction to my post, Noel suggested that I don't make a post at all, but I insisted that it had to be made, mainly due to the legality issue of such mod and just in case you and other members were not aware of it.

I am not sure why my reply to Brett about cleaning a dirty factory air box has anything to do with it and why you have plugged it in this thread.

In any case mate and since you're too sensitive to this issues for some weird reason, consider this feedback to be the last about your set-up and you can do as you please using your own resources and knowledge. I wasn't stepping on your toes but it seems you took it that way.

I suggest that you put some description around the pics you post on the forum instead of plugging them in and waiting for others to guess what they mean.

Good luck with your set-up and all the best.

Re: Air intake design & modifications


Hi Dave,

I got the MAF adapter from the same place I got the silicone joints. It is metal and had hole spacings of 70mm x 80mm so I only needed to elongate the holes a bit to have it fit the 75mm x 75mm spacing of our MAF sensor.
The silicone joints were formed 45deg and 90deg and a straight for the MAF adapter connection. They are 4mm thick with a 3-ply re-inforcing construction and tougher than rubber.
The black metal tubing was standard intercooler piping from an auto shop.
I went for the black colouring to give it the "stealth" look to keep it looking as much OEM as I could.


Jalal & Noel,

Did not take your comment offensively at all Jalal, just wondering if anything had changed, legally, regarding the SRI since all the previous posts and installs by Matt, Brett and others.
I had not seen the post you quoted before anywhere so having it coming out of the blue (so to speak) did seem odd and raised my curiousity that something might have changed.

I thought I explained what the pics were ?
First comment was that they were progress pics of my CAI and second comment was about converting to SRI for off-roading.
Before this were a couple of posts about preparations and ideas which were discussed with Dave.

There have been numerous posts elsewhere in the forum about headlamp bulbs and tyre sizes only being allowed for off-roading with the accompanying cautionary posts regarding legality and the use of a SRI for off-roading would also fall into the same concerns.

I endorse your warning to all the new members thinking of a SRI setup for everyday use and also point out that use of any oiled pod filter in the engine bay is also illegal unless it is fully enclosed, which a heat shield does not comply to. For this reason I will be using a dry-type pod filter for my off-road SRI to minimise the fire risk in the engine bay.
My normal everyday setup will still be, and has always been, a full CAI with the pod filter located in the wheel well as in the Cosmo setup.

As always, thanks for your continued guidance on legality matters of modifications.
