I purchased this manifold a few months ago to replace my rattly one on my 307 XSI (Same Engine as 206 GTI)
After lots of research i had this shipped from France, as it is the standard non heatshield model which cures the common rattle fault.
Comes with part number sticker.
I paid £100 for the part and the £23 to post it to the UK.
Second hand units are any where from £50-£120+ to buy but you will still have the common rattle.
