Don't fill them to max PSI! lol Porsche reccamends 36 psi in the back and 29 psi in the front. This setup tends to make the car push more in turns though. I go with 36 in the back and 32-33 in the front to make the car more neutral in the turns. The more air you add in the front, the more oversteer you will get. If you are going to do any auto-x or track work raise by 5-10 psi.

If you are going to get a new air-filter I would reccamend you purchase a BMC F1 air-filter. It costs about 70 dollars. I've had mine for a year now and have experienced no problems. It's supposed to add a couple hp. It is similar to the K&N but less oily and made of higher quality materials. The K&N's are known to cause MAF problems.
