i just bought my z with aftermarket wheels on it from the dealer (used) and it doesnt have the sensors for tire pressure, where can i get them to install and can i just throw them in or does the dealership have to program them into the computer or something.

 

You need to get them, and then the dealership needs to program your ECU to recognize them.

 

thanks. do you think theyll do it free since theyre suppose to be on the car, or will they say i bought the car as is with aftermarket wheels and so i have to pay for it?

 

You'll have to pay for them.

Check around -- there may be people selling sets (in fact, I think that I've got a couple of extra sets).

 

how much?

 

I've seen sets of used ones going from anywhere from $100 to $200. Just depends on how bad people want them or how bad somebody wants to get rid of them. Check the Private Classifieds under the Marketplace.
