I've just been and checked mine and its fitted as forge instructions but I think it's the opposite way to RR review.

^^^^ Sorry but that's the wrong way round (but is as Forge's original instructions before they were corrected).
NOTE: According to Forge, you should keep them that way around (unless replaced) so that no missed debris after cleaning can be placed on the turbo side. Apparently there is no disadvantage in performance.
I have new filters from Forge and they are now fitted the correct way around (my originals weren't - I insisted on following Forge's original instructions sheet and not JKM Jim's thinking) - My dyno plots indicate no difference in performance although the filters were not tested back-to-back on the same day.
^ The side taking air to the turbo.
In other words, the filter cones (concealed inside the canisters) should be the same way around as other cone filters are usually fitted.
It's written and fully illustrated in my review.
chopper:
surely if the golf r has same engine as my ed30 and the cupra r, why would it need different (pipercross) filters? are forge trying to pull a fly one here? have they realised the current standard filters arent up to scratch?
can we get hold of the golf R filters?

They all tune the same so if its not up to the job for one then how is it for the rest?

The question here is whether the Twintake is up to the job for Revo Stage 2+ on a K04 turbo.
Let's wait and see what Forge have to say.

Following on from this, today I received a reply from Forge (their technical guy) as follows:
"Hi Robin
I have done some tests on my golf mk5 GTi this has a big turbo conversion currently at around 400 BHP with the twintake and I have found that it perfectly flows enough G/S to produce 370 BHP.
After this I would recommend larger pipework and an open cone filter that has enough flow capability.
As you know we tried many different designs on the K03 / K04 cars and the twintake worked better than the open cone and any other design we tried.
But it seems that anything 370+ BHP the twintake will not flow enough."
So I hope this answers some of the questions raised in this thread :happy2:

Robin... What colour is the forge twintake? Is it red or black?? I'm concerned about its visibility!
