Ok my dads gf just got a 1993 mazda mx3. The only thing I know about it is that it is the sohc 1.6l 4cylinder. Where can I find performance parts i.e. Header and intake?

first off, you cant say stuff like:

"Uncle Bens or Rice-a-Roni...In the end, its still rice!"

and then give 2 links to riced out hondas!

but ... youre in luck, i've got some links to help get your feet wet w/the mx-3

this should get you started with the basic stuff

but if you want REAL power, you'll wanna swap....

the mx-3.com message board (http://www.mx-3.com/cgi-bin/ultimatebb.cgi) is another great place to search around for help.
