I just got my 2000 Cougar MTX a couple months ago. All I've done is put a K&N filter in. I wanna buy a performance chip, but can't find any except for these bullshit 10 dollar ones. Can anyone shed some light on my situation here??
One word of caution though. Performance chips have to be custom burned for you cars ECU and the mods you have on it to get the air/fuel ratios right. So if you get a chip now, you'll have to have it burned for a stock engine with a K&N filter. Then if you decide to go all out and get a new exhaust, headers, y-pipe, SVT parts, etc... you'll have to get the chip re-burned for those extra mods. So it's usually best to wait until you're done modding the car to get the chip. I'm not even really sure if a chip would give you that great of gains with only an air filter. So you may want to hold off on getting a chip until you have some other mods to accompany it.
Moderatley priced, umm well, i/e/h, intake, even know you have the filter, will get you a little better gains, try the injen, aem, or BOMz, on ebay they can range from 70-250+. For exaust trubendz makes some nice setups for the cougar, they will run you anywhere from 300+ and headers lastley, is significantly bigger upgrade, they are made by msds, all will give you pretty good gains, but the cougar in general isnt really that fast.
Depends on what you want your car to do or sound like. Free mods include the throttle hang fix (search for a how-to, they're all over this board) and throttle body optimization (which I liked, b/c you can do it all yourself, very hands-on).
It also depends on what kind of work you want to do. You can piece together a really great intake for less than an AEM or Injen, but it'll take more time and work. You may also want to try taking a weekend to tear down your UIM and clean the bastage out, it get's mucky.
