Hey, I've got a K10 1.2L 1991 Micra and I would like to squeeze out some more hp from it. Would it be possible to remove the airfilter pan and attach an adapter and a 3" sports airfilter? I opened the pan up and noticed two.. things? They look like sensors of sorts but I don't know what they do. I Also noticed a pipe going to the intake, I asume this is for the summer/winter modes. Is it safe to just pop the whole thing of and attach a tube with a filter instead? Thanks in advance!
