Title: Removing Airbox and Fitting Cold Air Kit
Post by: zdebx on 01 January 2010, 17:00
I'm not sure if I can do this myself or should take it to a garage, so decided to ask some advice.

Can I simply remove the airbox and connect the induction kit to the "flexi" pipe? The thing I am bit confused about is the 2 pipes that are connected to the air box?

One is the top one, where I have to connect the kit, but what's the bottom one and what is it connected to? I have to remove it too?

I got a 1.8 SE, if that helps

This is the same engine as mine:

And this is the kit I have:

Happy new year  :smiley:

The other pipe is for hot air on cold mornings. Your car will run a bit s**t till it gets warmed up if you fit a k&n

Worth adding that you can lose power fitting a cone filter due to heat soak issues.

sell the cone and buy a panel  :wink:

I thought that cone filters are actually good? Makes a nice sound, gets cold air to the engine and looks good too.

So what's the problem?

not a prob as such deb. there is a thread doin some rolling road tests on induction kits and modded air box with different panel filters and the result was the modded air box and geuine vag panel filter gave best performance results and sound good too.  :cool:

i have the same engine and is easy to install it.

First remove the air box and then fit the cone filter to the pipe , but if it do not fit take out the pipe and fit the cone filter on the otherside of the pipe because that side is bigger than the other one. Then you will need something to keep straight the cone filter and pipe.

What do I do with the bottom pipe then? It's connected both to the air box and something else...Can't figure out what, lol

And wouldn't it better and safer to get a stainless fitting kit, like this >>> http://cgi.ebay.co.uk/VW-GOLF-MK3-INDUCTION-FITTING-KIT_W0QQitemZ270441495916QQcmdZViewItemQQptZUK_CarsParts_Vehicles_CarParts_SM?hash=item3ef791bd6c

Not going to make much difference to be honest as it will still soak up hot air inside the engine bay.

Then why so many people go for cone air filters, if the hot air is such a problem?

People tend to fit them for the noise but it has been shown many times on rolling roads that they can cost you bhp.

Yes , you have to buy something to keep straight the pipe and filter  something like this  http://www.youtube.com/watch?v=U-n_VGbaqUQ

You just have to get out the air box and then fit the cone filter, but if doesnt fit well change the side of the pipe. (disconect completely the pipe and conect it again in the other side and then fit the cone filter. )

That is a hot topic of debate as many people myself included believe that when the car is moving there is always a fresh supply of cool air that far farward in the engine bay.

i had a cone filter like that fitted to mine and about a month later i took it off and put on the original airbox with a cold air feed going into it and its sooooooooooo much better & cheaper plus with a cone filter fuel economy goes out the window!!

the main reason is most people (esp those that drive a mk3) dont have alot of money hence driving a mk3 and therefore simply buy a cone filter for the sound when what is really needed is an enclosed induction system like a bmc cda.

Not going to make a lot of difference as you will still get heat soak.

You get heatsoak on a dyno cause the car aint moving and the heat builds up but out on the open road you have a fresh supply of cool air coming into the engine bay all the time.

Tis not the same. That's more to stop the car fron overheating by feeding air to the radiator. There is no where for the hot air to go in a when the car is stationary. like running on a treadmill and putting a fan on, its not the same as running down the street.

Trust me they make little or no difference.

Well, actually I want to fit one, because of the sound mainly. I'm not worried about performance too much, because it's not even a GTI...and I'm not going to race buses on the high streets.
