yes I also read the information about the aircon.
But there are several headers on eBay with almost the same look and nearly the same price, so I think they are also the same product. (never saw a hint of the manufacture)
And this shop is the only shop that had the information about the aircon. There is also written ' this item is sold as a direct fit' . But this probably mainly refers to the missing cat and lambda issue.
I have looked into my engine bay and in my opinion there is still much space from the header pipe of cylinder 1 to the aircon. I would be really surprised if the eBay header is so (badly) designed that it does not use this space.
The thing I like most at this header and what I think is the biggest advantage of it compared the supersprint one ( apart from the really nice price) is that this header will keep the original flex pipe. The supersprint header replaces it, which is not and ideal solution for a daily driver.
But I will still wait for someone having installed it
eBay says there are already 26 ones sold, so maybe one in this forum.
If I won't notice a gain in torque, power and response I will buy a used original header although this looks quite restrictive.
