There's a guy locally that polished the one's on the car I used to own and will be doing them on the car I am picking up tomorrow. Cost is around $140 a wheel. That's about a $85 to $100 less than I've been quoted by most other places. VERY nice work. I could check into this and get it done for you as a favor if you are interested. Let me know and I will contact him and firm up the price.
That's not intercooler that's that Bweavy guy These were done in aluminum. I sent a set out to get blasted & powder coated in clear when their done I'll post pics.
