I have been driving around with a K&N on my mystique for about a year and it's never quite run right. I went to the junk yard last week and found a pre 98 stock air box but it had no clips. I took it home and cleaned it up and bought some nuts and washers and bolts that I thought I could use to close it. Well those weren't going to work so after searching three junk yards I found a 98-00 air box and about 8 clips. My mystique is a 2000 and I like the way the pre 98 air box looked so I decided to stick with it. The car runs so much cleaner now. It picks up a lot better and it feels so much lighter when you hit the gas. She feels almost like a brand new car except for the suspension that firestone f-ed up. Anyways I can't believe how much better the stock intake works. I am going to try sleeperz's modification soon and see if that will further improve the preformance and gas mileage.
