Replace your standard plastic vents rings with CNC machined billet aluminium rings for that premium look and feel.
Fitting is straight forward. Simply remove the whole vent (it pulls out). Prise off the old plastic ring and then carefully and slowly fit the new aluminium ring (ensuring the slot in the aluminium ring lines up with up with the knob on the plastic heater vent). Fit one side and slowly work your way around ensuring it is fully seated using a screwdriver to help push the clips in if needed.
