- Unbolt your diffuser from your vehicle and unscrew the 4 fins. Place the fins on the outside or inside placements. Hold fins straight and re-align with the existing holes to remount. With the fin aligned, use a 1/8″ drill bit to tap the fins first to avoid splitting the HDPE (Do not drill all the way through the fins) and use your previous screws to hard mount the fin to the diffuser panel. Repeat step for each fin and reinstall your diffuser on your vehicle.
