Hi all together, I have a little question for you. I may have to install a sports air filter on my Golf 3 with 75hp, but not an open one, because I don’t get a TÜV test report. Now I want to know how much such a sports air filter really brings from the torque and PS or if this is all just talk in the article descriptions! I made a proper Remus sports exhaust, completely made of stainless steel, therefore the sound is quite good. Vie It’s easy to make him better with the K&N kit 🙂 Because I thought now he can blow out well, but then he should be able to suck well. Look forward to every answer. Ciao ciao Benni
