All you need to unleash the power of your Thunderbird are three things!
1- SCT Tuner
2- Cold Air Intake 2003-2005
3- Exhaust 2003-2004-2005 ( says 2003 but will fit 2004 & 2005 per this post. 2002 only fits 02 model.
Also recommend replacing ignition coils since these are often bad! They are cheap now, so at the least have a set on hand!
You can do the first two and then the exhaust at a later time if you don't want to do them all at once. The tuner alone will also yield results.

A must have for any Ford Thunderbird owner! Click here to view the SCT Ford Thunderbird Tuner that works on 1996-2014 FORD Cars & Trucks.

The SCT tuners are almost always better than the factory programming and well worth the money and usually pay for themselves IMHO! Same goes for the cold air intake. Just the money you save on air filters makes the cold air intake worth it! The SCT is the best tuner, so spring for it, if you have the cash.

Would you expect more improvement on 2002 since they were shipped? Didn't they raise 2003 hp quite a bit by reprogramming?

Ford added variable valve timing (VVT), to boost the engine’s output to 280 HP in 2003. You will get increased power/response by using the tuner on any model year. It's by far the #1 upgrade you can do on just about any car.

I have a 2002 and still looking for a cold air intake, all I have found is for the 2003 to 2005 do you know of one that will work for my 2002?
The K&N website says the CAI only fits the 2003,2004,2005 model. Unless someone here knows different, that is probably correct. Your other option is to go with the High Performance Air Filter which is what I use on my Ford Mustang. Link- http://amzn.to/2iVZ8g0

Some of these were already mentioned and some not---

Install a hi-flow Catalytic converter.
Advance the timing a few degrees.
Install a high power ignition coil.
Shorten the gap on spark plugs and get good plugs and new wires.
Use Shell or Sunoco hi-test.
Install a K&N air filter.
This is the cheap way, will get about 30 more HP and 2 - 3 % increase in torque.

More expensive...$500-$1,200…exhaust headers and cherry bomb or Walker straight thru mufflers or a Borla exhaust system. Will get you 10 - 12 HP and 1 - 2 % more torque. Plus a nice sound!

Because of the cars computer and its factory settings, changing the timing, might nictitate reprogramming by an expert. The other changes, probably not.

You could consider a performance chip such as SCT Flash Tuner---about $400, which touts a 28 HP gain.

If the air intake on a 2003 is changed to a K&N Cold air intake, does it require retuning the car or does everything still run OK, no codes flashing?
Car does not need a tune for the K&N CAI. The biggest performance increase you can do on the car though is the tuner! My son and I both have our Mustangs tunes and love it!
