Air filter options for RS2?

[sherv]

Hi,

Are K&N a good bet for an air filter upgrade for my RS2 or are there better options?

Cheers

The best option is OEM believe it or not.

Yeah Al (laser avant) just pm'd me with the same. Thanks fella

[AAH!]

If you want some go faster sucking and dumping noises you could go the cone filter dahlback route.

I believe just changing the OEM filter to K&N will make it a bit nosier as well

what about a forge 007 DV? These fine before any remapping has been done. Good for smoother drive?

For the standard airbox set up with standard power the OEN filter is best. Change it twice a year if you run >5K in urban setting. K&N needs to be cleaned and oiled, can cause MAF contamination and does b*gger all for performance.
Again use the S3 audi dump valve (stronger than OEM) and consider it a servicable item every 24-36 months.

There is no real evidence for performance gains with forge or non standard airbox/filter set ups with standard or even stage 1 remaps (up to say 360bhp with MRC).

Above that then you may gain a little apart from induction noise. Angus has a well tweaked RS2 which may well benefit from tweaking the above. Audi (and porsche) spent a lot of time on the 5 pot development and the RS2 airbox is excellent.

Oh and before you ask there is no benefit in removing the RS2 standard cats as they are little more than a mesh with non of the obstructive features of ceramic S2 cats !

Milltek exhaust ? maybe if going for big power.

A final thought is that the RS2 will become a collectors car over the next few years in RHD form. Even if you want to keep it for 'ever' now you may find it more difficult to sell with lots of 'performance' tweaks. BTW I do not mean a proper re map or 18'' cup 1 alloys

Hi Alastair, thanks fo rhe comments. performance wise it's going to be Milltek exhaust, mrc custom remap the 18" cup1's (fingers crossed) and possibly a little lower but just for looks as not going to track day it.
Just to confirm, you are saying that it is pointless to go for the full Milltek system just CAT back? Thanks. several hundred quids difference so want to make the right decision.

Oh and brakes probably eventually to the 993 big brake upgrade?

I personally swapped my OE air filter for a K&N panel filter and immediately noticed a slight improvement in throttle response. I could also hear the turbo working harder everytime I put my foot down by virtue of a more pronounced whistle

Cat back would be my choice...we are cross posting !

I chopped back and forth on my S2 with K&N. More noise but no more real performance. You may get some with a new K&N vs old OEM. I remain a non believer in standard set ups

I forgot to mention that I swapped my S2 airbox for an RS2 airbox at the same time which I purchased for £50 So all in all it was money well spent

Oh yes that is worth doing but its really the first as the MRC remap will test the standard set up.
I would look at the newer porsche monoblock options. Better by design.
