I have and 02 WRX fitted with a PPP kit and i want to know if fitting an inudction kit will make any difference to the power of the car. Also if i fit an induction kit will the engine mapping need adjusting.

I think it would be best to just get a better panal filter rather than an induction kit, people have gone for a sti, green and theres JR not sure about K n'N panal filters, these may make a small difference but you won't feel the difference as such. Final point on the induction kit. If this has not been calibrated in the ECU then you can also run into problems. Induction kits alter the flow pattern of air around the maf, this maf signal is the primary load reference for the ECU, used for controlling boost, fuel input, ignition timing, knock control and various safety limits. If this signal is 'wrong' then the ECU doesn't know this and may not add enough fuel for example.
On full throttle, it has no way of knowing what the actual airflow is, some inductions alter this signal more than others......you pays your money and takes your chances ! Taken from Andy F

Stick with a quality panel filter
