How to make your own air box!

[NightRIDA]

Ok guys.I do not take responsibility for your shitness.
So let's get on with it. This is probably the easiest & cheapest mod you can do for highly noticeable performance.

Things you'll need:
-Sheet metal (1m x 1.5m)
-Cardboard (the bigger the better)
-Paint (optional)
-Screws & screwdrivers
-Rubber mallet (for bending the sheets)

So.... start by making templates out of cardboard.
When you're happy with the result,simply transfer it onto the sheet metal.
Make sure you include little tabs to screw the box to the body.
Now you can do the cutting with tin snips which would take ages for a crap result.I used a jigsaw with a blade for metal,makes life easy.
Drill the holes for the screws on the box off the car, then mark then in the car.

I'm only focusing on the air box because you can make the plumbing to your desire. (eg. silicone hoses, or whatever you can find)

when you're happy with the result you can paint it.(or not)
Here are some pics that might make it easier. feel free to ask anything as I can make them to order if you're interested.

looks good there ive made one from strut tower to headlight and on a charged car massive blower whine.

looks great... whats the induction sound like?
and what sort of ducting are you using because I want to upgrade to 4" but dont really want to pay 100 bucks for the one advertised online (i forget where)

I want to buy one but i can see freight being alot cuz im in melbourne...

So this is a DIY home job of the MACE CAI kit...

not bad

The ducting i'm using is 4.5" semi-flexible construction piping/tubing.
The sound is not as loud as before it was enclosed,but you still get the "vaccum track". lol

VS 666 if you're really interested i can send it flat so you just have to bend it!

Can I suggest you find some pipe work that ISN'T convoluted.
The convolutions actually disrupt air flow and cause it to tumble inside the piper. Smooth bore pipe is much more efficient.

You'll notice bugger all difference, but every little bit counts.
Good job on the box too, looks the goods.

Thanks,yeah I should aye! Stuff the "clean look" ! GO PERFORMANCE!!

good right up,
i would do it but nooone sells pod adaptor for the efi vk

[ari666]

man that pipe is gonna cause so much turbulence...

Im currently in the process of doing this mod, Only difference is i picked up some Thermal shield foam from Clarke rubber to line the inside, comes with silver lining and adhesive already on it, only costs $25 per meter and when you only need 20cm makes it cheap and should really help keep the box temp down.

How did you go about securing the air box in place?

[NightRIDA]

thats what the tabs are for!!

[bogan_vk]

looks the goods, neat job!

[RoboticCherry-Coke]

thats what the tabs are for!!

My bad, I must have read over that bit.

Very nice result. As said before the pipe isnt a huge issue but some aluminium pipe and some silicone elbows if you want a little more for performance and looks even though its probably only going to be 1/4 of a KW or less.

Also Ive seen silicon pipes made to order from $2-4 USD per meter on a Chinese website but minimum order is 500 meters so that doesnt really help for you, but then "performance companies" stamp a logo on it and sell the elbows for $25 and straight lengths from $20-50, huge profit from them.

The best part about a CAI system isnt the POWAHHHH that you get (woo- 2rwkW if you're VERY lucky lol), its the ability to run a damn-near unrestricted flow path for ambient air, assuming you put a large free flowing filter panel or pod in your airbox.

Means that when you stomp the throttle at idle, when rolling along, whenever- you'll be getting colder air than you would from a stock setup or (god help us) an under-bonnet pod filter/hot air suction machine. This generally equates to a snappier throttle response, a few extra Nm (which is where the rear gains are) and a full hektik noise.

i ran a 90mm poly- pipe CAI setup on the wagon on the wagon for a few WSID runs, was all sprayed temp-proof black and with no other mods i dropped 0.5 seconds on average on all my runs. 60ft times (while crap) was where i got my gains. Gained 1mph

Here's how it looks now!! Brand new MAF + Genuine Rubber!!!!!! wouldn't change it.
