1Working Principle: Improve the aerodynamic characteristics by enhancing the transition between the high speed airflow below the vehicle and the free airflow around. 2Main Purpose: Provides space for the airflow under the vehicle to slow down and expand, thereby providing pressure recovery by providing a degree of airflow filling. 3Good Performance: The vehicle rear bumper splitter will not cause excessive airflow separation and resistance, and will maintain driving safety and stability. 4Abs Plastic: The rear bumper splitter is made of excellent Abs material, with good toughness, wear resistance, aging resistance and extended service life. 5Replacement Part: Perfect for decoration, improve your vehicle safety and racing style, which can replace the old or damaged rear bumper diffusers.
