I don't know if any of you seen it but I posted a message a little while ago about putting on a K&N cone filter. Well boys, I did it and it isn't too bad of a deal.... I just removed the airbox on my 97 Mystique 2.0 and attached it right there. It works really good but its a little doggish off the start in town. I think its cause my car gets REALLY hot when I just go slow around town. Is there any way to fix this? And I notice my fan doesn't kick on till I am on the A in NORMAL on my temp guage. But other than that, on the highway it has improved gas and the sound is awsome. The only thing that I don't like is that if you notice on the Mercury Zetecs, right past the first air sensor, there is a huge black rectangular shaped box that comes off the intake towards the front of the vehicle. Now as far as I know it seems empty and there is a sensor in the bottom of the tube its connected to... What can I do with this, and do I need it? All of you should know what I mean if you have seen one. Now I look at all my friends Ztecs they have in their cougars and they don't have this peice on their intake. I am confused. I want to rip it off but I need some advise.... All will be appreciated.
