Home made cold air intake

[taylorsvr]

before i start ill just say that this only cost me $20 and bout 10 mins

ok so it was a really hot day and was thinking, there must be a cheaper way for a cold air intake rather than spending the odd $200 on some plastic moulding intake kit. So after i had read some ideas on home made intakes i decided to rig one up myself.

for this mod i kept the standard air box and KN panel filter.

All thats needed:
-an old radiator hose (i picked up a $20 S-shaped hose from super cheao auto, but made sure it would be long enough)
-tin snip (or the rite sized hole saw)
-and a metal coat hanger.
-drill/drill bit

so all i did was cut a hole in the side of my air box a bit smaller the diameter of the hose (so it would be an air tight fit)
and then i cut another section out of the splash gaurd where the other end of the hose sits and drilled some holes to fix the coat hanger inplace to support the hose up. give the hose i good yonk to see if would stay in place, so i had no need to fix anything down.

and that was it, drove round after that and my temp gauge was quiet lower than it was before hand.

i might try and find a fitting to go on the end so it looks prettyer, kinda like an exhaust tip but obviously in sumting lighter and bit smaller, but u get the idea.

looks like a great idea to me, but i can't see that little pipe flowing enough cold air to make a difference. it simply wouldn't overcome the hot air coming in the standard intake hole

thats why i suggest fitting a wide mouh at the end, then the air is just forced, besides im running to intakes now, i have noticed the diff tho

i hate too sound like a prick but the splash guard is called the splash guard for a reason.... youre probably going too have water problems.

how would water run upwards through an s pipe into a air box then rise high enough through the filter and then up the intake pipe into the engine. 4wds dont seem to have problems with rain going into there snorkel, and besides i dont uasually drive through water that deep.

i wouldnt think its likely when you put it like that i was just saying why mount it where theres an obvious chance of water getting into it being that holden put a splash guard there obviously because water splashing up could be a problem.
why take the risk?

I cant see water being a problem. I doubt water will even make it up that far, and if it does it probably wont even touch the air filter, but if it does the filter would turn it into a mist, which like water injection it will bump up compression a poofteenth and lower intake temp. The end result it gets turned to steam and you also have a slightly cleaner engine . It wouldnt have time to corrode components. If the hose somehow became submerged in water the air would be drawn through the standard inlet and probably wouldnt have enough vacuum to draw water up the hose.

I dont have a problem driving in the rain with my VS S/C factory OTR CAI. You only have to worry when you get a mass of water in the intake and bend rods (which Ive seen cases where its happened).

why would you have any problems with water with a super 6 cai? , the whole thing with water in getting in cai`s has to do with the pvc piping type ones that people like too mount behind fog light holes or generally closer too the ground,

wow... That little intake is one way to starve a motor of air...

*sigh*

Go all the way, Or don't even go there at all...

What you have made is nothing more than trying to breath through a straw if you are under water......

Because its exposed to anything oncoming - dirt, bugs, water and rain splashing off the grill.



Still low chance of water making its way up a low-mount CAI and if it does it will only be in small amounts making it little threat. But youre not wrong, worst case scenario it can do damage. But try to avoid driving into lakes

lol @ hozy's post

hmm well it seems people are agreeing and dissagreeing on this under car intake. i think ill have another look in my engine bay to remount the intake pipe. there is a channel it can sit on, i think it has one of the heater hoses running along it to front of the bumper than bak round again, not as much of wind path but probably safer away from water. but can anyone please enlighten me on how this CIA will be long enough to join into my air box?

It sits on top of the radiator/fan shroud, hence OTR (over the radiator) CAI. Sit it in place, the second bit of plastic connects up to go down to the airbox and you either have to buy the proper bottom section of the box from holden, or just cut a bit out so it fits in.

Smart idea.

[chrisdoesitbetter]

put a bit of flyscreen over the end of the intake hose (under the car) so if you are sitting behind a truck you car wont swallow rocks and cow dung.... as long as your happy with it thats all that matters!!
