any truth to this? and if so how would one change it

[michael_]

Read this on another forum (generic car forum) and am curious to know if there is any truth to it and as per the title how one would change it.

Actually, give you the hot tip, all GTi's imported to AU (probably all VW's actually) still retain the EU air inlet and aren't changed - which means its 50/50 air intake from outside air and engine bay air (they do this for cold climates to help with cold start etc etc).

So for slightly better fuel econ. just get the air inlet changed so its 100% outside air

Hmm, that's interesting. Although, parts of southern Europe get pretty damn warm anyway. :iono:

[ApexTwin]

I'd be keen to change it if that's the case. How can you tell?

Can you show us where you read it? Or perhaps ask the author if it's true?

It certainly sounds interesting and worth following up.

[SSS_Hoon]

yeah its true, if you open the bonnet and look at the intake you will see where the it gets the cold air from there is a black plastic cover there right near the grill part, take it off and look inside you will see what he is talking about.


the bottom there is a hole there to get inside engine bay air, and also there is a bit of plastic sticking up that sorta blocks the cold air coming in too.

you could take the cover off been told it makes the DV louder and can perform a tad better too.

Here's a pic of what they are talking about. To me, for Aussie conditions it's crazy to have a set up like this.

There are two ways I can think of to do something about it.

Cut out the flap that I've circled in red as it seems to be a restriction and block off the intake into the engine bay. This would direct cold air into the intake instead of engine heat.

Or,

Remove the intake box altogether and fit an intake hose to direct the air stright into original intake hose.

Oettinger sell and airbox to remedy this http://www.oettinger.com.au/4039.jpg

APR/Carbonio has something that looks identical (Funny that since APR is part of Oettinger)

Question is, if you don't have an upgraded chip, or exhaust, etc, is it really worth $600??!!

I found a place in the UK that sells them for less. Even with postage, it still wouldn't be as expensive as APR or Oettinger.

http://www.awesome-gti.co.uk/vw%20golfmk5/engine.html

At £165 ($419 Aust) it would be a better buy. This is the one I'm going to get.

[michael_]

and i wonder if it will void warranty

[Jamie GTI]

and i wonder if it will void warranty

The only things that void warranties are mods that have been proven to be the cause of the fault. If your window doesn't wind down, they can't blame a intake change and not fix it under warranty.

However if your engine blows up and it's because it's not receiving enough air, then the mod will be at fault.

[michael_]

well in my experience any alteration even minor such as this would void a warranty, i mean in my case i would simply put the OEM part back on before a service so they would be none the wiser.

Hey Jamie,

How much did they quote you for shipping on this from the UK? As I'm still waiting for them to reply to me on the same item.

Another place I've asked is $280 + $70 shipping (in USD) from NGP Racing.
http://www.ngpracing.com/Merchant2/merchant.mvc?Screen=PROD&Product_Code=CI100012&Category_Code=mk5intake

But unless you can install it yourself with the instructions that they all say are provided, it's really not much of a saving. Basically shipping costs from all these online places are a killer. :frown:

[ApexTwin]

Yep, we always get raped on shipping charges. :frown:

What Jamie posted above is correct. :thumbsup:

I found the Carbonio for US$237 here (http://ecodetuning.com/shop/cart.php?m=product_detail&p=660).
I've contacted them about shipping cost, and just waiting for a reply...

Thanks ApexTwin! This price definitely looks more attractive, assuming you get the sports filter as well, right?

Do you mind keeping us posted on the shipping cost? :w00t:

[ApexTwin]

I'll let you know as soon as they get back to me.

[michael_]

anyone interested in maybe a group buy of them? see if we can get the cost down ?

[dodgey]

I might be, depending on total price :D

[SSS_Hoon]

wouldnt cutting that plastic bit out and sealing the factory one be the same benifit, without the carbon fibre look though?

There's a bit more some substance to the Carbonio/APR/Oettinger part other than looks, to justify the premium price. It does come with a sports filter that replaces the stock one, to maximise the air intake. Probably worth $50. :laugh:

Whilst the sports filter looks just like chicken wire held together within a rectangular plastic frame, its gotta work better than your DIY backyard job.

But arguably you could also go out buy a new air filter. However I'd stay away from filters like K&N, as the oil off it can damage the mass air flow sensor. Need to stick to dry-type filters.

lol i added to the cart and checked shipping it came to $531 USD for just the shipping LOL.

I wonder if someone from like oetinger here would do a deal for 10

Guy Harding would be up for that IMO. Dunno about the savings possible, but he'd certainly do it. Sounds like you just arranged yourself a gig. :w00t:

yeah just spoke to guy, if we can get enough interest i will contact him about a group buy

Bloody none of the online retailers have come back to me with shipping.

And yes, I saw the ridiculous UPS quote on that site. Forget it! :mad:

I put in my details but didn't get any result for shipping cost. Maybe because I'm on safari.
We'll see what they say when (if) they get back to me - as that shipping calculation michael_ got is ridiculous.

[Jamie GTI]

Hey Jamie,

How much did they quote you for shipping on this from the UK? As I'm still waiting for them to reply to me on the same item.



I never bothered to ask to be honest. After being quoted $699 from Oettinger to supply one with a filter I figured even with something like $70 postage, I'd still be better off.

I can't believe that shipping makes a $237US ($305 Aust) intake to $531US ($685)!!!!

I'd be interested in a group buy as well if the price is right. If not, I'll wait to the missus goes to England later in the year and get her to pick one up for me.

Umm, US$531 is the shipping cost and does not include the US$237 for the product itself... It is however, UPS Express and not standard UPS (FWIW)

Alright Jamie,

Awesome-gti came back to me with an awesome shipping cost of $78 GBP on their CAI.

When I saw this I instantly thought I would change the intake but thinking about it when the car is stationary engine bay heat would enter the air box. Once the car is moving the air entering from the grille would place the air box under a greater pressure than the engine bay thus providing 100% outside air into the intake.

Looking at the box setup I don't think a venturi effect would be occurring.

I'm not a scientist but if you think about it...the air is getting sucked in not pushed/forced in...
Say you had 2 straws in your mouth and you sucked on it...you would be getting air from both the straws...as long as there is an opening to the engine bay...the intake will suck air form both outside and inside...
Correct me if I'm wrong...as stated...I ain't no scientist...:iono:

[vRStu]

Intersting that you all look toward Awesome GTi in the UK. Here in the UK we like to buy from the US to save money.:tongue:

I know somone who has the Carbonio, which incidently was imported from the US for less than the Awesome price, and it has been removed to make way for an EVOMS kit, also imported from the US.

The gains from it didn't seem to be that great to be honest.

Thats what I thought at first and agree that when the car is not moving and at low speeds the air would be sucked into the intake from both the engine bay and outside air intake.

Once the car is underway than the air travelling into the air box via the grille would force its way into the intake and the engine bay, that is assuming that the quantity of outside air being supplied to the air box via the factory intake is enough to meet engine requirements.

I understand what you are saying about the two straws. Say your mouth is the air box, one straw is the opening to the engine bay and the other is the outside air intake. Once you start travelling the intake will force air into your mouth while your are trying to suck from both. What would happen is the forced air will supply you with as much air as you can suck and the rest of the air would travel out the other straw (into engine bay).

I hope this makes sense.:confused:

Ok...has anyone ever used/seen a vacuum cleaner:biggrin: ...normally on the handle part...there is a vent that you open/close to control the suction...
I'd think it's the same principle applies here...to have the most efficient suction/airflow from the cold air outside to the intake...there shouldn't be any opening in between...
Even if the air is forced in, if there is an opening in-between...the forced air will create vacuuming effect and draw the air from the engine bay to the intake...
Hhmmm..I say bring on the Myth busters :thumbup:

Vacuum in the air box would not occurr, as the box setup could not create a venturi effect.

Below from Oettiger website

VOLKSWAGEN Golf 5 GTi Engine Accessories

OETTINGER RAM-AIR

With the standard intake most of the air stream passing through the front skirt is released in to the engine room. Once the carbon Ram-Air collector has been fitted, the complete air flow is directed in to the air filter box. Due to the optimised flow form and the excess pressure created, more air is fed to the engine as the speed increases. This in turn leads to a noticeably improved response and increased power.

The noble component is manufactured in Carbon and impresses with its first class fit and finish. The OETTINGER RAM-AIR intake is available with or without sport filter insert.
