retrofit TPMS
 

My 997 was produced right before Porsche started to make it a standard option. I got a great deal buying it with only 900 miles on it. All of the options I wanted and none of the bling options that I did not want. But the one exception is TPMS.. My car does not have it. Is it possible to retrofit the Porsche TPMS on my car? Some of the aftermarket options like kind of kludgey and the Porsche TPMS integrates into the instrument cluster nicely.
