What Cone Air Filter

[B]Doug, I just noticed this bit in your opening post - did removing the MAF screens completely have any noticable effects, either good or bad, on the car's performance? [B/]

Not any noticeable affects for me.

[B]Was there a problem that you were trying to fix when you did this? [B/]

No problems before. We had discussions on the yahoo group on why the RS2 MAF only had a screen on the inlet side(and it is different) - so I took both off - It might get slighly better airflow though it - the mesh must restrict it to some extent. The conclusion is that you need something on the inlet side to straighten/ make the air flow more uniform over the wire - I think!

Also, why is a cone filter better in theory to a better panel filter in the original airbox? Is the air intake a major source of restriction in the S2's power potential?

With a cone you are not restricted by the 80mm inlet duct that all you air would have to flow though - but that is channeled from the outside - should be cool - you have to be careful with the cone for heatsoak - the reason I have one is becasue the original airbox would not fit with my big turbo. I also have a 100mm ducting force feeding cold air to the cone filter on mine.

I'm not going to get much better than this - although an electric fan when stationary might help with heatsoak.

I also have a rubber seal on top of the heatshield(not shown) to seal it to the bonnet. We were getting low intake temps when we were thrashing the car for a couple of hours, 25degrees C inlet temps measured on vagcom IIRC - although it wasn't exactly warm outside.

It depends... Why do you want a cone filter anyway, as opposed to a decent performance panel filter in the original airbox anyway? Surely by having a cone AND boxing it off, you are literally reverting back to the original set up? Apart from the noise, of course? :confused:

The extra sound is one thing indeed, but you know what, I just can't get all those securing clips for the airbox secured (the one on the back and on the left side; how do you guys get those secure!?)

[Vagsport]

Depending on the size of your fingers (bananas) with effort that leaves your fingers bleeding! (3B)

Regarding the clip on the back of the airbox - after doing this several times over at last meet on several cars I found a real easy way of doing it - it's amazing what a few(a lot) beers can do.

Use a small spanner - rest the open end on the lip of the box and with the shaft of the spanner in the kink, at the top of the clip, you can just lift and it drops in place - REALLY easy.

If you don't understand I'll take a couple of pics tomorrow to show you how easy it is.

A lot harder on the 3B airbox, Doug.

Don't know what the 3B is like - any pics? - the spanner definitely works for the ABY box.

[Vagsport]

No pics, Doug, but picture a KV / NG (2,226 / 2,309cc) Coupe and you get the picture. Worse on the 3B, as the box goes even further into the wing. Fine if you have bog standard fingers, but if you have fingers like a bunch of bananas or Frankfurters, you'll be cursing the engineers who designed the 3B S2!

wow man, my fingers are more like those of a large insect :wacked:, I can get 'm in there a bit (3B) but I have to go so far down that the hand comes to play and I absolutely can't do didly squat with my hand twisted in there, tried pulling the clip up with some makeshift device but I think that warped the clip more than do anything else
Now you know why I'm thinkn' of an easy way out like an open air filter

[Greg_S]

yeah 3B's arent nice, very awkward. Easy to get ABY ones off, just use a long screwdriver to pop the ones of theback.

and the front clips take the bulb cover bit out then u can get to clips nice and easy.

I find it easier to remove the complete airbox to gain acces to the filter on my 3b, takes 5mins max!

Yes but how long does your refitting take? And how do you do it?

[martinjs]

refitting takes about 5 mins also
i find its lug with the fixing hole on the side of the airbox which causes the problem, tricky getting it past that pipe which leaves the downpipe (with the bung on the end) trick is to guide the lug round the back and under the pipe.

HTH...hard to explain

[Rob W]

Hi Zenith,i must admit the reason i put on cone at the time i did was,the grief i had with the kin airbox one day,so went out found a kit and junked there and then,adecent heat shield is a must though.

[newsh]

Doug a really cool thing in that pic of your engine bay is the WGFV sitting up there where you can see it, have you got a close up of how you did that?

The 3b one is an absolute PITA to get to...

Or is it an ABY thing anyway ?
