I would put the origin, putting another type of filter (in my opinion) does not make sense or will improve anything in a TDI engine, which the one who aspires and puts air is the turbo and not the crossing of valves ... it is not good to suppress the aspiration line, the resonators that it brings are studied by something, a separate subject I will tell you that some of these filters filter less impurities and harm the flow dirtying the measurement or thread sensor and giving error to气流的度量...这些产品的卖家没有说。总结:您的汽车是由工程师设计的,以可靠...但是您决定。问候jherru!
