98-lgt Posted November 2, 2010 Share Posted November 2, 2010 I just intstalled 06' STi cat back on my car today and it ran 100% normal. Just put the ebay intake on and now the car won't idle, bog out under 1500 rpm. There was only 2 hose connectors on the intake, so on one of them, I just put a filter on it. Anyone know what is wrong? Link to comment Share on other sites More sharing options...
