Hello municipality, after I had bought a new air filter for my OMI and then had to go already 22,- € for, I just bought a sports filter from Jux and Dollerei at Ebay. Costed 4,90€ plus 3,- € shipping. So you could not do much wrong, I thought. Joyful and full of tingling in the belly because of new handicrafts, I immediately got into my garage and plucked the large air filter, all of it out. After that I then got the new air filter. n Sportluftfilter on the intake pipes screwed. Folded great. I was also enthusiastic about the pass rings, which were there to compensate for possible deviations. After that I made a test drive and was very disappointed. A really annoying sound came out of the engine room at once and made the beautiful slide away to a rally ride. At least as far as my ears are concerned. Well, I left the “thing” on it first because I had no desire anymore, the old box s Now I’ve been driving with the “Sporti” for two weeks and wondering about more performance. Please don’t look stupid……I can’t believe it either. But every morning I drive the same route, a little 25 KM, to work. There’s also a long piece with a small mountain, which you have to drive up. And right there…..I suddenly got a nice “grin” in my face. Maybe I also had a kind of facial cramp, but I think I’m imagining that the OMI now easily drives up the mountain, where he had real trouble before and I didn’t just have to switch down from the 3rd to the 2nd to get up. My OMI just has the X20SE engine with 115 hp and then has a small weakness attack at 16% incline. But these seizures are blown away, since I have this stupid rally filter on it. Can someone explain this logically to me now????????? I mean, by another filter you make a 115 hp car not yet 13 0 PS….or do I now have small males crawling and pushing out of the filter while accelerating????? Dear greetings, Omega2367
