Less drag can mean a bit of a boost in fuel efficiency. Spoilers also act to reduce lift without adding more weight to the car. This can help keep the car more stable at higher speeds and improve traction without affecting its performance by adding excess weight.Most spoilers on the market requires you to drill holes into your trunk. One little mistake will ruin your vehicle, not to mention it is very time consuming. Our spoilers are designed for easy installation, quick Sunday morning project. The spoiler is attached using automotive grade double sided adhesive tape. To ensure the spoiler stays attached, we recommend the surface of the trunk is cleaned throroughly as it will help the spoiler to remain in place securely. After the spoiler has been installed, please refrain from washing your car for at least 3 days. This will help the glue to set in and cure.Specifications:- Condition: 100% Brand New- Fitment: Compatible with BMW 4 Series G26 Gran Coupe 5 Door Fastback 430i M440i i4 eDrive xDrive. - Year: 2021-2026- Package includes: 1 rear trunk spoiler, 1 roll of adhesive tape- Finish: Glossy Black- Material: High Impact ABS* Note:- The roof spoiler is painted in glossy black- Installation instruction is NOT included, professional installation is recommended if you are unsure of the installation process.- This is a non-OEM product- Compatible vehicles above for reference only ## Features - ✅Compatibility: Compatible with BMW 4 Series G26 Gran Coupe 5 Door Fastback 430i M440i i4 eDrive xDrive 2021-2026.
