    Keeping your view clear in all weather is crucial for safety, and that starts with effective wiper blades.

    Best Aftermarket Replacements

    When you venture beyond OEM parts, you'll find a wide array of aftermarket options. These blades often offer advanced features like beam-style construction for better pressure distribution and all-weather coatings. Here are some of the most popular choices, categorized by their general price point:

    • Premium Tier:

      • Bosch ICON: A top-tier beam blade known for its durability and excellent all-season performance.
      • PIAA Si-Tech: Features silicone rubber, which lasts longer and applies a water-repellent barrier to the windshield with every wipe.
    • Mid-Range Tier:

      • Rain-X Latitude Water Repellency: This popular beam blade applies a Rain-X water-repelling coating directly to the windshield.
      • Trico Force: A rugged and durable beam blade engineered for high performance, especially in windy conditions.
    • Value Tier:

      • Michelin Stealth Ultra Hybrid: Combines the aerodynamics of a beam blade with the focused pressure points of a conventional blade for reliable, quiet performance.

    Attachment Style

    The 2020 Subaru Forester uses a standard J-Hook attachment for both the driver and passenger side front wipers. This is the most common type of wiper arm, making replacement straightforward. The rear wiper, however, uses a more specific Roc Lock 3 attachment. While many aftermarket rear wipers come with the necessary adapter, it's crucial to confirm compatibility before purchasing.

    How to Install

    Replacing the front wiper blades on a Forester is a DIY-friendly job that requires no tools.

    1. Lift the Wiper Arm: Gently pull the wiper arm away from the windshield until it locks in the upright service position.
    2. Release the Old Blade: Locate the small plastic tab where the blade connects to the J-hook of the arm. Press this tab and push the blade downwards, away from the hook, to release it.
    3. Install the New Blade: Slide the new wiper blade's connector into the J-hook until you hear an audible click. Give it a gentle tug to ensure it is securely fastened.
    4. Lower the Arm: Carefully place the wiper arm back against the windshield.

    For the rear wiper, the process is similar, but you will need to unclip the plastic cover over the mounting point and use the specific adapter provided with the replacement blade.

    When to Replace

    Wiper blades are made of soft rubber and degrade over time due to sun exposure, dirt, and general use. For optimal visibility and safety, you should replace your wipers every 6 to 12 months. Don't wait for a downpour to discover your blades are failing. Signs that your wipers need immediate replacement include:

    • Streaking: Leaving lines or trails of water on the glass.
    • Chattering: The blade skips or vibrates across the windshield instead of gliding smoothly.
    • Splitting: The rubber edge of the blade is cracked, split, or tearing away.
    • Squeaking: A loud, unpleasant noise with every wipe.
