What Cone Air Filter

[Doug_RS2]

I will probably be replacing my airbox with a cone.

What have people fitted to their S2s? What size can you get in there?

What diameter is the MAF inlet (80mm?) and how have cones been fitted?

I remember looking into it a while ago and the ITG Foam filters looked good but there were reservations of the foam getting sucked in? Should I be putting my MAF screens back on??

Cheers all

I bought a big fat K&N cone filter supplied by dialynx. It has the 80mm dia. for the MAF it just is held on by a hose clip. Only thing is there is no heatsheilding supplied. You will have to make something up to do this job. Something i havent got round to doing yet.

Audiman, any idea what part number that cone has? I've been trying to find a kit for the S2 but there isn't a standard K&N cone kit for the S2 I think.
Any help appreciated, I want a cone

Hi Doug happy New Year,i fitted a K&N earlier last year,its was meant for use on 2.9 24v Cosworth(as used in a ford granada)

Hehe - this is an old post of mine! Rob - Happy New Year - Not heard from you in a while!

I got the big ITG foam filter and I made a heatshield for it from the double skin aluminium from Merlin Motorsports - it's dead easy to make - just get some card and make a card shield, then use that as a template for the aluminium - it can be cut with scissors. I got an old boot seal form a golf to use on the top edge to seal it to the bonnet when closed.

Rob, is it the kit shown below? Was it a direct fit?

[Rob W]

Yeah thats the one,the cone fits on ok if i remember correctly 80mm is the MAF diameter,this cone was 79mm so it fitted nice and tight,even before a circlip.

Ok thanx, I might go for it then

I have a cone (K&N) in mine, had it fitted for last couple of years without any hassle. Heat is a big problem and I made a cover for mine from a sheet of aluminum from B&Q (about £15 for a square metre). It works fine while you are moving fwds but if you are stationary for any length of time it heats up just like anything else.

Here's a picture....I retained the existing heat shield which was bolted onto the side of the airbox and made a snug cover with the ally and made a small kink so that the strut for the bonnet has a place to rest

This is the kit i am getting for my rs2

i tried a few filters on my car but i have decided to get this from
dahlback racing.

its about 150 quid but i think its worth it, looks like the tool for
the job

gain and loss balance

All the talk about cone filters has lightened the tuning fires again.

I own a 285Bhp 3B (tuned by Mihnea ) and I now have an open K&N-filter in the standard airbox, a difference to the original filter could not really be feld.ops:

What does a cone filter bring an S2, bhp or torque wise?

The heat seems to be a big problem. Iddle running for some time is a problem, does the car stall??
Has anyone found a GOOD heatpreventing solution, other then bringing the cone in the wheel arch??

oh is that where it sometimes goes?
Yes ideally I would actually like the end element to be somewhere other than the engine bay....
is it possible to get it all the way to just behind the (right) rs2 grill? If so, would it give the intake a too long path? R u guys gettin' me

[Vagsport]

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:

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?

Was there a problem that you were trying to fix when you did this?

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?
