Any ideas? Air filter U pipe..

[s2_bo]

Hi guys. I have just ordered a new 80mm Apexi 500-A021 to replace my stock aribox.

Has anyone converted to one of these universal filters before?

I was hoping to fit it with a nice fat 3 or 4 inch chrome U pipe.

I have never done the filter on a S2 so was kinda hoping that someone here had some good pointers.
I was also gona reroute some cold air from under the right side of the engine.

anyone got any ideas i would really appreciate it.

Thanks.
Bo .

Hi

Try to make an relly good heat sheild for the filter.
And maybe an pipe from the front up to the filter area.


I have tried open air filter for a while now, first the soud is nice.
Yester day i switched back to my original air filterbox, the car ran smoother and better.
I belive with an open air filter, the hot air from turbo and ex mainfold is sucked in to the filter. That leads to hotter intake temp = loss of power ?

Tomorrow i will buy a open panel filter for the original air box.

Boost 1.4bar 3" ex rs2 IC.

This is my opinion, dont know if im right.

Thanks pelle, i will consider that.

I was gona try to run a cold air pipe up from the bottom to flush out the hot air but i'm not sure yet what sort of heat shield to use. i think the stock one will just look a bit ugly.

Lucky my step dad works for Lorient Poly Products. they are the wold leading manufactures in fire and heat seals, im sure i can blag something good the keep the warmth out from them. .

cheers

I have just fitted the same filter, at the same time I ordered an 80mm adapter plate so that a silicone hose would fit snugly.

I also used a 180 degree stainless U bend from a Porsche exhaust system that was going cheap on ebay, but there are many other methods of fabricating this bend, just search this forum. 964 Stainless Steel Final Muffler Bypass G-Pipe

As far as a cold feed is concerned I used a 100mm flexible flue that you can buy from most plumbers and directed it from the filter to the lower font grill, seems to work well.

I am also currently using the original heat shield which is ok but could be better with a little thought.

As soon as NTL have been and re-installed me in the new house I will post some pictures for you , unless you are going to castlecombe.
