206 cc inspection problem?

Hello friends ; my car is 206 cc 2.0 engine 2002 model peugeot. The vehicle will be inspected in June 6, but the vehicle has an open air filter and it is costly to return to the original. I asked the publishers but I couldn't find it. a showbox for the vehicle to pass the inspection (lower air hose cannot be found out of production). There is no point in the car, how do I want something additional to go through the examination?

I have 1.6, because there is no spare wheel in the fabrica output.
