Do these caps snap into the factory vent openings or do I need fasteners?

These are designed to snap into the factory vent positions. No screws, adhesive, or brackets required — just push them into place until they seat.

Will these match my dashboard if it's faded or discolored?

These caps are new OEM black. If your existing dashboard has faded significantly over time, there may be a slight shade difference. Test-fit before committing.

Are both front and rear caps the same size?

Front and rear vents on this model use different cap sizes. Both are included in this set — one for each position.
