Adding heated seats to my 02 i35?

[osu9400]

I have an 02 i35 with leather seats. I would like to add heated seats. Are the guts already in the seats, or do I need to buy new seats completely?

Any suggestions?

Thanks.

You need new i35 seats equipped with heating, plus you need to have a different type of power cord installed inside the interior to power up everything(i.e. power seats) and seat heaters. Costs quiet a bit of $$$.
