Look at my thread "Homemade Cold air Induction kit for Hdi90: part two" it works much better.
It is easier to make and doesn't heat up that much.

Hi all
I´ve made me a Cold air Induction kit, which I would like to share.
I find Zack´s system very sexy, but I´ve needed something more simple, as I am leasing the car.
The price is just over £100 for the main parts.
Additionally you will need some bits and pieces that you probably have lying on the shelf.
For the project you will need:
One pcs. of 180degre Silicone Elbow 65mm £15.61
http://www.ebay.co.uk/itm/BLACK-SILI...item3f0b06e398
One pcs. of 90degre Silicone Elbow 76mm £16.71
http://www.ebay.co.uk/itm/BLACK-SILI...item43a7d46b6b
One pcs. of 45degre Silicone Elbow Reducer 63-51mm £7.05
http://www.ebay.co.uk/itm/45-Degree-...item7dbd777b5a
One pcs. of Straight Alloy Tube 65mm £7.29
http://www.ebay.co.uk/itm/65mm-Alumi...item3efaeb0f18
One pcs. of ASH Carbon Airbox, outlet 76mm £54.95
http://www.ebay.co.uk/itm/Universal-...item43a06195cc
Total £101.61
You find the best price for all this on the AP MotorStore eBay Shop, however if you don’t want to by the Hose Clips in 5 or 10pcs. bags
You find the best price on the AP MotorStore online Store. http://www.apmotorstore.co.uk/
JCS STAINLESS STEEL HOSE CLIPS:
One pcs. of 55-70mm
Tree pcs. of 60-80mm
Tree pcs. of 70-90mm
Further more you need a short length (300mm) of 76mm air duct to go from the Air box inlet, to somewhere under the headlight.
Here is the “How to”:
When you are cutting Silicone tubes, tighten a Hose clip around the tube and use it as a cutting ruler.
First you take the “65mm Straight Alloy Tube” and forge one end like a trumpet with the pin of a hammer, the outer diameter has to fit firmly inside the 76mm hose.
This is done to prevent obstruction of the airflow inside the hose.
Then you take the “180 degree Silicone Elbow 65mm” and cut 45mm of one leg.
Attach the cut of piece to the other leg with the “65mm Straight Alloy Tube” as in the photo.
Then you take the “90 degree Silicone Elbow 76mm” and cut 90mm of one leg.
Then you take the “45 degree Silicone Elbow Reducer 63-51mm” and cut 70mm of the 63mm leg, and cut 90mm of the 51mm leg.
Then you take the “ASH Carbon Airbox” and cut half of the inlet and half of the outlet, to ensure a tight fit in the engine compartment.
Remember to smoothen the edges, and free everything from dust and burrs, you don’t want any debris hitting the turbo.
Then you put everything together as in the photo.
Next you remove the standard filter and all the tubing, except for the 90 degree plastic tube attached to the turbo.
Fitting the Cold air Induction kit:
First you put the hose assembly in place, and tighten it with a Hose clip.
Be careful with the vacuum hose, you can bend it gently with your fingers before connecting it, to avoid stressing the connection.
Then you place the intake air duct under the headlight, and push it as far as you can towards the hollowness behind the front bumper.
At last you move the wires from the battery to the side, and toggle in the “ASH Carbon Airbox” between the air duct and the hose assembly, and tighten it with a Hose clips.
The direction of airflow I am using is:
Inside of the filter cone facing the engine.
But I don’t know if that is the right way, I have been mailing AP MotorStore, and they haven’t answered.
The only thing left is to enjoy your work :cool:
Does it do the job?
My first impression is better sound, a little improvement of torque but maybe not the amount of power that I´ve expected.
The throttle response has declined a little too.
Maybe the engine gets too much air now, a remap would solve that but as I am leasing the car it is not an option.
A chip box solution may be the answer.
It is easier to make and doesn't heat up that much.
