Features and Effects
The center diffuser blocks airflow from behind the rear axle to prevent air from entering the rear bumper, thereby reducing unnecessary drag and directing all airflow to the underside of the diffuser to generate strong downforce.
The conical shape of the left and right side tunnels increases the flow velocity of the air passing through them, drawing the air beneath the body toward the rear.
The left and right end panels reduce drag by smoothing the airflow and suppressing turbulence around the rear bumper.
By creating a gap between the rear bumper and the diffuser to enlarge the exit opening toward the rear, airflow beneath the body is improved, enhancing overall downforce and cooling beneath the body.
　
　
Important Notes on Diffuser Installation
This product cannot be installed on vehicles equipped with the stock exhaust or an exhaust system equivalent to the stock system due to differences in layout.
