Heres a pic:

Im wondering if i can run twoopen cone filters on the forge twintake so get rid of the carbon canisters and just run open cone filters with the twintake pipework,
Just wondering if anyone has done that ? And i assume is should be fine or even better than a single filter intake am i right ? Dont want to spend money on a intake

You could I suppose.

I've never been a fan of the Twintake to be honest as the narrowest portion of the intake is still at the MAF.

It doesn't matter if you have 10 filters on it and huge pipes as this is the narrowest point.
Also,if flow improves as a result of putting 2 filters on,it implies that the original spec wasn't up to the job.

The old ITG flows enough for 600+bhp with a single filter.
Ok rant over.... A pair of decent quality foam filters such as ITG or Pipercross should work.
