Cover Cap For Plenum Chamber Cover, Black.
The Porsche Cover Cap for Plenum Chamber Cover is a genuine OEM finishing piece designed to secure and complete the plenum chamber area beneath the windshield. Finished in black, these caps neatly close off the ends of the plenum chamber cover, preventing debris and moisture from entering while preserving the clean, factory look of your Porsche.

Fits:
  • Porsche Boxster 986 2.7L 1999-02
  • Porsche Boxster S 986 3.2L 1999-02
  • Porsche Boxster 986 2.7L 2003-04
  • Porsche Boxster S 986 3.2L 2003-04
  • Porsche 996 C2 3.6L 09/01-2005
  • Porsche 996 C4 3.6L 09/01-2005
  • Porsche 996 C4S 3.6L 09/01-2005
  • Porsche 996 TURBO 2000-05
  • Porsche 996 GT2 2001-05
  • Porsche 996 GT3 MKI 1999-02
  • Porsche 996 GT3 MKII 2003>>

What This Product Does:

  • They act as end caps / cover caps on the cowl / plenum / windscreen base / vent grille area, covering the ends of the trim or grille to provide a finished look.
  • They help prevent water, debris or dirt ingress into the cowl / dash vent cavities by sealing off the open edges where grille meets body.
  • They provide aesthetic finish and protection to fasteners, edges or joints in the cowl / plenum area.

Signs / Symptoms Of Wear, Damage Or Missing Caps:
  • The cap is broken, cracked, faded, or missing, leaving the edge exposed.
  • You see visible fasteners, rough edges or openings at the cowl edge / grille.
  • You notice water ingress, dirt or debris entering behind the grille or cowl area (especially in rain or car washes).
  • The appearance is inconsistent (one side has cap, the other doesn’t) — visually unbalanced.

Why Replacement Matters:
  • Restores a clean, factory-finished appearance to the cowl / grille area.
  • Helps keep out water and debris, protecting the underside of the cowl, vent passages, and interior of the dash.
  • Prevents rust, corrosion or wear to components under the cowl that might be exposed if edges are open.
  • A small, low-cost part, but gives a big touch to visual completeness and protection.
