306 platinium 2001model

Hello friends, as a result of my research on the internet, I did not find air intake (air filter kit) for my 306 platinium vehicle, 106 and saxo models I found, I found another one related to 306, he said that he was for gti and the kit was troubled in the settlement ..
The reason I want something original is: there is a pipe coming out of the engine, I think it is made for oil, it does its job, and of course it has a nice look and sound.
I would appreciate if you help (306 platinium 1.6. 2001 model)

There are those who connect the crank filter to the end of that pipe made for master oil and leave it idle, but I do not know technically, but I come to those who do the same way by making holes in the pipe used for the open air filter and sticking to the original system in the same way. but frankly, I find it expensive, apart from the really professional ones, it can be bought as cheaper by collecting it in pieces, but this is a matter of choice.
