erm, for 1.3 carb, i guess you can go brother and buy the RAM, then you need to get the adaptor to fit into the ram, cause im using it on my car now also, with some unbranded open pod filter. so far so good, no problem ;) can also buy the adaptor to fit in the custom stainless steel pipe too. so means you got the air-ram for your carby, then get the adaptor to get the stainless steel air-ram and also the ram itself, then add on the filter at the end of it, in the end, you manage to bring the filter further away from the engine giving it good position for CAI purpose and also nice look stainless steel ram attached to your filter and also in your engine bay ;)
