Having followed the work that Mr 5 has done on his intake which utilises the stock air box, I felt that this setup has a lot of potential.

I have previously used a BMS single, but didn't really like the sound - I want stock sound, with a better flow of cool air.

My solution uses 2" silicone hose, clamped together. Where the hose connects with the stock air box I have flattened out the end of an aluminium coupler and put an o ring behind it to achieve an air tight seal. The hose is obviously smooth on the inside, which gives good flow - even on the 90 degree corners. I have managed to route the hose that prevents it from being crushed by the wheel liner - achieving something that to my eye looks pretty stock.

You will see below that I have cut the hole as low as possible on the side of the air box. I did this in an attempt to prevent turbulence between the air coming in from the top (via the panel filter) and the air coming in from the hose - I think this has worked pretty well, although it did cause some fitment issues to get the hose to clear some engine components.

You will also be able to see that I have trimmed a couple of holes in the brake air duct so that it can pass some air through into the compartment close to the filter - it is not a ram air effect, but does allow cool air to be sucked into the filter from outside rather than it being drawn in from the engine bay.

After a few attempts with different hoses to get the hose to route how I wanted it, I have achieved as below:

















To return my air box back to stock, almost - I have sourced a 2" cap and fitted an o ring behind it to seal the hole in my air box. Again, when fitted, this looks pretty stock - but obviously would stand out to a trained tech. It does work well though. This is the cap, not fitted though obviously:

Looks good. Any plans for dynos?

Yes - not for a little while, but I will be doing something in the not too distant future.

[cstavaru]

Looks very professional, congratulations !

[NiVeDh]

That looks great. Good work.

[cn555ic]

Nice and clean....looks really nice...

[scalbert]

Very good.

I should have a stock intake shortly and will be fabricating a new lid, ala, Dinan. If it works out, CAD drawings will be available.

ur the man

Great job man!!
I really need to do what you've done with the silicone hoses but I'm having a hard time trying to find something flexible with an ID of 2.75"
I also need only 3 ft of it and people are selling only 12 ft lengths.

you should get a group of people who are interested to split with you, i would be interested

It appears to be a very good location of the new intake stud

You may want to cut the protruding part of the hose clamps or use smaller clamps for a clean look.

There are a few simple rules to make an installation looking professional. No more than two base colours in the engine bay, cover new cables with black shrink tube or similar, screws (and hose clamps etc.) should be of the right length, cables should be hidden or be straight or have smooth bends and be fixed if visible. Sorry for preaching, I’m just visualising how to finalize similar ongoing mods in my car.

Great work. Looking forward to seeing results.

That may end up being a common problem. Perhaps we all "share" the costs once a common method is determined.

I didn't end up using the flexible hose that I bought. I achieved this with 1 x 45 degree elbow, 2 x 90 degree elbow and a 3" to 2" reducer - this provides the perfect fitment imo.

Looks great. One suggestion would be to use T-Bolt clamps on the visible tubing, that would really clean up the look.

don't know if you've heard of www.mcmaster.com, they sell mainly commercial items might be able to find something that'll help you out.

they've have all kinds of vacuum hoses and air ducts from varying sizes and types of material... just have to search their site

I found exactly what I was looking for.
Thanks a bunch!!

love reading about these modified stock air boxes. makes me want to do the same mod. can't wait for more info on your setup, OP.

You can try www.siliconeintakes.com and www.intakehoses.com , they carry mainly intake-related parts.

I wonder if 2.5" tubing would work instead of the 2" used ? I like the routing from behind the power steering reservoir, it spares me from relocating some fan relay. I think a 2.5" would be a bit strangled in that area...or not ?
