Porsche Repair Questions? Ask a Mechanic for Answers ASAP
Thank you for your question, my name is ***** ***** I am a fully qualified vehicle technician with over thirty years in the trade, hopefully I can help.
The original spec for the 2002 Boxster S (986) 2.7 L and 3.2 L engines is 400 cell.
The 200 cell would normally be for a sports performance upprage to enhance power but comes at the cost of the emission output.
I hope this answers your question but do please feel free to ask any further details by replying to this thread, many thanks
Yes I would use the 400 cell stainless steel unit, once fitted you should have no further worries for quit a while.
(in that area anyway).
