The original Carbonio was not much of an improvement over the stock system.
There's a bit of history in the rest of this...
The VWRacing intake is essentially an enclosed ITG system.
APR were for a while based with VWRacing,in Milton Keynes,and during that time,the VWRacing intake was developed,along with ITG.
If you look at the design of the VWR and current APR Carbonio intakes,you will notice a number of similarities,especially in how the filter element is totally enclosed.
Awesome were with APR,then not,and are now the UK distributor for APR,when APR Europe moved off to Germany after some "issues" with VWR in the UK.
There was a big restructuring of the way APR was being run in 2014,when Mangrove Equity took over,and things have worked well since.
With respect to the VWR system particularly,it does work up to at least the requirements of hybrid and smaller BT systems.
The ITG on which that is based is good for over 600bhp,although it's no looker.
