If installed by the dealer the parts and labor are about $300-400; some people negotiate this into their deal. I just negotiated the installation so I had to provide the parts.
The front and rear
wings are about $30-40 on ebay
The
Wheel caps... this is where it gets tricky.. if you have the v6 the
wheel caps are about $40 maybe less; if you have the v8 the caps are about $200. Here is the trick if you have the v8 and want to don't want to spend $200 on
wheel caps and are handy. Since the v8 are not sold in Korea (just based on research I did at the time) the
wheel caps they sell for the v8 for $200 are actually modified orignal v8 flying H
wheel caps. People take the V6
wheel caps heat them up with a heat gun or bake them in the over(225 for 15 min) and peel them off. Then they take their stock flying H
wheel caps heat those up and pry out the flying H. Once that is done they put the genesis
wings from the v6 caps in place.
I hope that makes sense lol.
