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.

Engine Bay Trim Lock Catch, Satin Black.
The Porsche Engine Bay Trim Lock Catch is a genuine OEM fastener designed to secure the engine cover trim panels. Finished in satin black, this lock catch provides both durability and a factory-correct appearance, ensuring your engine bay remains tidy and properly assembled.
Sold Each.
x4 Required Per Car.

Fits:
  • Porsche Boxster 986 2.5L 1997-99
  • Porsche Boxster 986 2.7L 1999-02
  • Porsche Boxster S 986 3.2L 1999-02

  • Porsche Boxster 987 MKII 2.9L 2009-2012
  • Porsche Boxster S 987 MKII 3.4L 2009-2012

What This Product Does:

It’s a fastener / clip / retainer that secures the engine cover panels / trim cover in place, locking them so the panels don’t come loose under vibration or movement.

Symptoms / Signs It May Need Replacement:

  • Loose or rattling engine cover trim — the panels or covers may not sit flush or may vibrate.
  • Trim shifting under movement or at speed — cover panels may lift slightly or shift.
  • Broken, cracked or missing catch / fastener — so the original clip no longer secures properly.
  • Misalignment of panels due to one side no longer being held securely.
  • Wear or plastic fatigue — the catch may have broken due to age, heat, or repeated removal.

Why Replacement Matters:
  • Restores firm, secure mounting of engine bay trim and cover panels — reduces rattles, vibration, and the risk of trim components coming loose.
  • Maintains factory look and finish — using a correct satin black OEM catch ensures the trim matches the rest of the engine bay aesthetic.
  • Protects trim edges and adjacent components — loose trim can rub on paint, hoses, wiring or other parts, causing wear or damage.
  • Prevents further failure / damage to other catches — when one clip fails, others can become overloaded and break too.
  • Because this is a small, inexpensive component, replacement is relatively simple but helps avoid bigger issues (lost trim, replacing panels, etc.).

Whether you’re restoring a classic model, replacing damaged trim, or upgrading to modern components, Design911 offers authentic Porsche plastic covers and high-quality aftermarket alternatives to match your car’s original finish and function.

Available in a wide variety of types — from underbody panels and engine covers to scuttle panel trims and clips — these covers provide structural protection and visual refinement across your vehicle.

Boot Lining Plastic Covers
Boot lining plastic covers are protective and finishing panels located within the luggage compartment (boot/trunk) of your Porsche. They serve both aesthetic and functional purposes, helping to shield internal metal surfaces, wiring, and components from wear, moisture, and cargo-related damage.

Engine Bay & Mechanical Covers
Durable plastic guards that protect engine components from dust, heat, and debris while enhancing under-bonnet presentation.

Underbody & Chassis Covers
High-strength undertrays and shields that protect the chassis, suspension, and drivetrain areas from corrosion and road debris.
