A must-have aesthetic component for your G20! Designed to accentuate the factory body lines, this trunk spoiler adds a subtle but transformative appearance that you won't want to miss out on!

Performance aesthetic to match the performance-oriented G20!

The G20 is a great example of a wolf in sheep's clothing. These models pack performance under the hood, have a comfortable but sporty suspension, and have a feature-rich interior however from the outside of the vehicle you would never know. What the M340 lacks in appearance is made up by its comfort, technology, and definitely performance.

Though you can be more than happy with the vehicle's drivability ECS felt that people should know the G20 is a performance-oriented model! After a lengthy process of scanning, design, and testing we came up with a trunk spoiler spoiler that compliments the factory body lines yet completely transforms the look of the vehicle to properly represent the performance attributes of the 3 series.

Upgrade to performance-focused styling on your G20 with the ECS Tuning Gloss Black Trunk Spoiler. This trunk spoiler was engineered in-house and designed to follow the curves and lines of the body to offer a more aggressive look that matches the factory appeal of the vehicle. The spoiler is crafted of a durable UV-stabilized ABS polymer to achieve its deep high gloss shine and provides a sporty style that's sure to set your vehicle apart from the rest. Installs with no drilling, cutting, or modification of any kind required. After you have everything lined up and the surface clean of any contaminants, simply remove the liner on the already attached high-strength dual-sided tape and press the spoiler firmly onto the trunk lid. Install the spoiler as-is or with proper surface prep, this spoiler can be painted to any color you like!
