Performance suggestions
I got a 04 automatic rx8. I'm not trying to race it or anything, I just want to know helpful tips into making my car faster. I recently ordered a cold air intake. Any suggestions in what parts I can add to my car?
Thanks in advance

Depending on which cold air intake you'e getting, it's more likely to reduce power than increase it. You can get a slight increase in power by replacing the cat with a plain midpipe, but you'll increase smell and usually have the CEL on all the time. As well as running illegally in most places.
Mazda did a really good job of tuning the intake and exhaust in the RX-8. The only way to get significant power gain is to turbocharge or supercharge. But that's expensive, and virtually a life style decision on these cars.

The biggest easy gain you can get is to trade the car for another one. And no, I'm not joking. You can pick up about 40hp just by trading your 8 in for a manual transmission one. Even trading for a 2006+ automatic will be a 10-20hp gain.
You picked the slowest least powerful RX-8 ever made.

Weight Saving
Definitely agree. Lots of low-hanging fruit for taking out weight. Easiest is to keep tank half-full. Gas weighs about 6+ lbs. per gallon. If you don't mind more frequent fill-ups, 5 gallons down nets you 30 lbs. off. Small, but relatively painless and doesn't cost any $$. Not for everyone, but something to consider.

Life After 8K RPM....
Agree with RIWWP.. Trade it for a 6spd manual 8.
Get rid of the CAT, that will give you a little boost
Other than that BHR just released their new headers claiming 25whp for $ 1700

That's actually relatively cheap compared to other upgrades for these cars. That nets you about $68/HP while a catbackl exhaust or cold air net you about $400/HP.

The BHR tests that I've seen results from were all on 6 port cars too, so it might not even make the advertized gain on a 4 port since they already flow less. 4 ports kinda suck.......
I'm told that, much like Vin Diesel, the BHR guys have a fair amount of rotary nitrous experience.

Next on the agenda, read the new owner's sticky thread repeatedly until your mate beats you senseless for mumbling RX8 info in your sleep or, worse still, during lovemaking.

Next up, if engine health is not in question, try some of the inexpensive mods listed in this thread:

Then, once you have worked through that and your budget is once again balanced, ask yourself the following question: "Exactly how quickly do I really want to lose my license?" The answer to that, bearing in mind the existing power available to you natively, should give you an idea whether or not to pursue the original query. Meanwhile, try maximizing the usage of the existing power by using the paddle shifters to make use of the 8's existing power.
