but so far I cannot find it down under the intake where the WSM says it should be.
the 16V has a very different intake and occupies a lot of the space where all the docs I have read say it should be.
looked in WSM, read Clarks garage writeup, PET.
anyone know where it is located?
searched threads but cannot find.
