I put one of these on last Friday.
Fairly straight forward. Remove the intercooler and you are looking right at it. A swivel 14mm socket will make your life easier if you do this job.
When I took my old one off, I discovered the original one had a dried bushing that was starting to crack, so I was pleased that it needed a new one anyways. That made my purchase feel smarter.
The perrin stop is metal and about 4x heavier and thicker, and much more stout that the original one which is plastic!
Holding both in each hand, the original just feels pathetic.
