Professional Cryogenic Metallurgy & Coatings In Cumming, pretty neat place..... got the header I bought from mckenzietj thermal coated, they did a pretty nice job, coating looks good, 1 week turnaround..... they did it for $160, which seems to be competitive....... haven't installed it yet so I'll update this thread periodically and let you guys know how it holds up..... Next on the list from PCMC: coating the stock TMIC with thermal dispersant..... the guys over a GrimmSpeed tried it and dropped intake temps by about 25%, IIRC..... the thread's on Nasioc somewhere I think..... and I haven't decided if I want to do a hack paint job on my wheels or powdercoat them, but if they get powdercoated I may give these guys a shot.....
