Front Bumper GT3 Smile Air Vent Kit..

Vent Kit: OEM GT3 Vent, mounting brackets, and hardware.

Front Bumper Air-Outlet Grille Porsche 997 Models.
This air vent can be retro fitted into model 997 bumpers giving the GT3 look.

Fits:
Porsche 997 2005>>
Porsche 987 Boxster 2005>>
Porsche 987 Cayman 2005>>

The front of a GT3 has a look and feel that sets it far apart from any other automobile in its class. The sought after upper air vent screams speed and aggression, but unfortunately it’s only available on a true GT3. Installing one of these vents on a non GT3 bumper can be very problematic, one slip of the saw and your bumper cover is unusable. Rennline's GT3 vent installation kit turns a daunting task into a very simple one. No more tracing, cutting, praying, grinding, and gluing. Just attach the fixture, cut the profile, and mount the OEM vent with the supplied brackets and hardware. It’s truly that simple.

Note: All of these components are designed to work with factory bumpers and vents.
Note: Pictures may not show actual product
