If you have the S variety, you are going to want an S bumper. Specifically because the base model bumper will not have a hole for the middle radiator.
Also, the 2003-2004 variety (commonly called the 986 V2) has a different-looking front bumper cover, in addition to some other parts.
As a new 986 owner, you are definitely going to want to keep the
986 parts catalog bookmarked. It is an incredibly useful tool (not just for verifying fitment, but also for identifying part numbers to search for the best deals possible)
