The pic above taken from SKUNK2 website is the REAL Skunk2 Pro Series Throttle body (Comes in black or hard anodized). The thing I noticed about the fake, was that the minor details like the machine chamfers round the edge was missing, it was just a straight edge unlike the original as point out by the red arrows above.
I was lucky that I have been staring at the TB for months (couldn't afford one ;p), therefore I was able to notice the difference.
So take note, before parting out your hard earn cash for fakes.
Note: This is not a post to promote SKUNK2 products, but as a means to keep everyone aware that there are fake SK2 TB in the market.
