Adding this shark fin spoiler in a suitable position will force the airflow to advance in advance, from laminar flow to turbulent flow, reducing frictional resistance and pressure drop resistance, thereby reducing the drag coefficient, and also releasing static electricity, effectively reducing the adhesion of dust and dirt to the body, reducing Noise, etc., can also provide some pressure to stabilize the body Specification Material:Made Of High Quality ABS Plastic Color:Black Fitment: Universal fit for most cars Package included: 10x shark fin wings 10x adhensive tape Notices 1.Wipe and clean the roof before installation to make it stronger 2.Make sure you take the proper measurements so they line up perfectly 3.Since the size is manually measured, please allow an error of 1-2mm 4.
