Source of Boxster factory service manual
 

I am trying to find a source (hopefully free, online) for the boxster factory service manual. There is a link in this forum but it is dead.
My immediate need that would help is an assembly drawing and parts list of the air intake path, beginning with the air intake, air filter, MAF, throttle body to the head. I am trying to track down an (apparent) vacuum leak on the air intake side and I don't have a smoke machine. Any suggestions/pointers are appreciated.
No codes are being thrown and the CEL is off.
Thanks

Shop manuals do not include parts lists.

Service manuals available
 

Trying to spread the word but https://charm.li has service manuals for 97 to 2013 Boxster and others Porsche made over that time, along with many many other cars and trucks.

Considering that even Porsche did not print any service manuals after the 2003 model year, whatever they are pushing is questionable at best, and while they may contain snippets from the earlier models (much like other websites that have partial manuals for the very earliest cars), they probably do not have all the 1997 - 2003 updates and corrections, which are literally hundreds of pages alone.

Old, out of date, or incorrect manuals can actually be worse than none at all. Go with the Bentley unit.
