If you have any of these parts for sale or know where to get them cheap let me no.
1. titanium grey front end grill aftermarket
2.cold air intake
3.exhaust
4.side sills titanium grey
5.carbon fiber hood.

does any one know if have a cold air-exhaust will void my warranty in any way.

also has any one painted there rims(does it look good). I helped paint my friends 05 srt4 rims and they look awesome but i don't wanna **** mine up.

also if i bought the diagnostic plug in for my car to change the air/fuel ratio would that make much of a difference.

Can you program your welcome note to say different things on the center screen display, and can you put names of your radio stations. And to the right of the screen display i noticed that there is other sysmbols which show how high you ac is on and what not my doesn't light up and i was wondering if theres a way to make it turn on.

-thats it thanks guys

Im not a Mazda 3 person but i have not seen any hoods or grills yet for your cars.

As for intake and exhaust, there are more and more each day but you have to look around.

Only a few intakes sofar have the CARB aproval that is required toe stay smog legal. Other then that any warranty should not be affected by intake and exhaust unless the problem is directly related to it. The dealer might try but you should win in the end.

As for the diagnostic port, unless you get a specific tuner, i would not mess with the computer using simple diagnostic plugs. SCT has their new X-cal 2's now that can do anything you want basically.
