Vehicle and Part Overview

The 1999 Porsche 911 (996.1 generation) includes the Carrera (C2 and C4) and GT3 models. These vehicles utilize a staggered set of hook-style wiper blades designed to maintain contact with the glass at high speeds.

  • Driver’s Side (Left): 22-inch (550mm) blade, featuring a spoiler to keep the blade pressed against the glass.
  • Passenger’s Side (Right): 21-inch (525mm) blade, specifically curved to follow the contour of the 996 windshield.

OEM Part Numbers:

  • 996-628-901-08 (Driver's side with spoiler)
  • 996-628-901-07 (Passenger's side)
  • 996-628-901-02 (Complete set)

Recommended Part Types:

  • OEM (Bosch): Bosch was the original factory supplier. The Bosch Twin Spoiler set (specifically the 3397001582 / 582S kit) is the standard recommendation for factory performance.
  • Aftermarket: Valeo or PIAA (silicone) are high-quality alternatives for heavy rain environments.
  • Fitment Note: Avoid generic "no-name" blades. These often lack the correct curvature for the 911's windshield, resulting in "chatter" or uncleared spots in the driver's line of sight.

Safety and Fitment Notes

CRITICAL SAFETY ADVICE:
Wiper blades are safety-critical components. In a rear-engine car like the 911, maintaining high-speed visibility is paramount. Poor quality blades can lift off the windshield at motorway speeds or fail to clear road grime effectively, significantly increasing the risk of an accident in poor weather. Always opt for OEM or high-quality specialist brands.

Installation Pro Tip:
When changing wiper blades, place a folded towel on the windshield directly under the wiper arm. If the spring-loaded arm snaps down while the blade is removed, the metal hook can easily crack the windshield.
