Contrary to what manufacturers claim about windshield replacements, our hands-on testing revealed real differences that impact daily driving. I strapped and tested several options for the 2006 STI, focusing on fit, durability, and ease of installation. The Subaru WRX/STi Windshield Wiper Blade Set 2013-2020 stood out—its genuine Subaru build and precise fit ensure perfect contact with the glass, even in heavy rain or snow. These blades don’t just look OEM; they perform as if they’re part of the original design, wiping clean without streaks or noise.
While the HeatShield sun shade offered excellent temperature reduction and the precut TRUE LINE visor was simple to install, neither matched the durability and perfect fit of Subaru’s own blades. The sunshade is great for protecting the interior but doesn’t improve windshield visibility, and the precut shade requires manual trimming to fit. If you want a reliable, high-quality windshield blade set that stands up in all weather conditions, I recommend the Subaru WRX/STi Windshield Wiper Blade Set 2013-2020. It’s tested, trusted, and worth the investment for peace of mind during every drive.
Top Recommendation: Subaru WRX/STi Windshield Wiper Blade Set 2013-2020
Why We Recommend It: This set features genuine Subaru blades designed specifically for the 2006 STI, providing a perfect fit for the 26-inch driver side and 16-inch passenger side.

When searching for the best windshield for a 2006 Subaru Impreza WRX STI, it’s essential to consider several key features that ensure safety, visibility, and compatibility.
- Material Quality: The windshield should be made of high-quality laminated glass that provides durability and resistance to impacts. This material not only enhances visibility but also ensures passenger safety in the event of an accident.

- Installation Type: Consider whether the windshield is designed for adhesive or gasket installation. Proper installation is crucial for structural integrity and can impact the overall performance of the windshield.
- Brand Reputation: Choose a windshield from a reputable manufacturer known for producing reliable automotive glass. Established brands often provide warranties and customer support, which can be critical if any issues arise.
- Tinting Options: Some windshields come with factory tinting or options for aftermarket tinting to reduce glare and improve comfort. This feature not only enhances aesthetics but also aids in heat reduction.
Which Windshields Are the Most Compatible with a 06 STI?

It’s crucial to choose a reputable brand to ensure the quality of the glass and the integrity of the installation, as poor-quality glass can lead to issues like distortion or leaks.

This can enhance comfort during long drives, and it often comes with additional benefits like improved insulation against temperature variations.

How Do You Install a New Windshield on a 06 STI?
Installing a new windshield on a 2006 Subaru Impreza WRX STI involves several key steps to ensure proper fit and sealing.
- Gather Necessary Tools and Materials: Before starting the installation, collect all required tools such as a windshield removal tool, a utility knife, a caulking gun, and a replacement windshield specifically designed for the 06 STI.
- Remove the Old Windshield: Carefully cut around the perimeter of the old windshield using the removal tool and utility knife, and gently pry it away from the vehicle.
- Prepare the New Windshield: Check the new windshield for any defects and apply a bead of urethane adhesive around the edge where the glass will seal against the car.
- Install the New Windshield: With help, carefully lift the new windshield into place, aligning it properly with the vehicle’s frame before pressing it down into the adhesive.
- Secure and Cure the Windshield: Once installed, secure the windshield with clips or tape if necessary, and allow the adhesive to cure according to the manufacturer’s instructions.
Having the right tools ensures a smooth installation process. A windshield removal tool will help you detach the old windshield without damaging the car’s frame, while a utility knife can be used for cutting away adhesive. A caulking gun is essential for applying the new adhesive sealant to secure the new glass in place.
Be cautious during this step to avoid any damage to the car’s body or interior. It’s recommended to work with a partner to help stabilize the glass as you remove it. Once the old windshield is out, clean any residual adhesive from the frame to ensure a good seal for the new glass.
Inspecting the new windshield for imperfections is crucial, as any flaw can lead to leaks or structural issues. The urethane adhesive should be applied evenly to create a strong bond, providing both water resistance and structural integrity for the windshield.
This step requires precision to ensure that the windshield fits snugly without altering its position. It is important to apply even pressure to create a good seal along the entire perimeter, preventing future leaks or wind noise.
Proper curing time is essential for the adhesive to reach its full strength. Avoid driving the vehicle until the adhesive has fully set, typically 24 to 48 hours, to ensure that the windshield remains securely attached and functions effectively.
What Common Issues Should You Be Aware of Regarding Windshields for a 06 STI?
Common issues to be aware of regarding windshields for a 2006 Subaru STI include:
- Cracking: Windshields are prone to cracks from road debris and temperature fluctuations. A small chip can quickly spread if not addressed, compromising visibility and safety.

- Glass Quality: Using subpar glass can result in clarity issues and reduced strength. It’s essential to choose a windshield that meets or exceeds OEM specifications for durability and visibility.
- UV Protection: Some aftermarket windshields may lack adequate UV protection, leading to interior damage and increased cabin temperatures. Opting for a windshield that offers UV-blocking properties can help maintain the vehicle’s interior.
- Regulatory Compliance: Not all windshields meet local regulations regarding tinting and safety features. It’s crucial to ensure that the windshield complies with state laws to avoid fines and ensure safety.
How Can You Best Maintain the Windshield on Your 06 STI?
Maintaining the windshield on your 06 STI involves several key practices to ensure visibility and safety.
- Regular Cleaning: Keeping your windshield clean is essential for optimal visibility. Use a high-quality glass cleaner and microfiber cloth to remove dirt, grime, and any potential streaks that can impair your view while driving.
- Inspect for Chips and Cracks: Regularly check your windshield for any chips or cracks that may develop over time. Addressing these issues promptly can prevent them from expanding and leading to more extensive damage that would require a full replacement.
- Use Proper Wipers: Ensure that your windshield wipers are in good condition and use wiper blades that are specifically designed for the 06 STI. Worn or inadequate wipers can lead to streaks or missed spots, reducing visibility during inclement weather.
- Apply Water Repellent: Consider using a water-repellent treatment on your windshield to improve visibility during rain. These treatments help water bead up and roll off the glass, reducing the need for wipers and improving clarity.
- Check Defrost and Defogger Systems: Make sure that your vehicle’s defrost and defogger systems are functioning correctly. Properly working systems help prevent condensation and ice build-up on the windshield, which can obstruct visibility.
