Appears to be a mod, not factory. Do they actually go anywhere or are they just a dead end?

They are interesting looking, but not having a rear engine needing an intake, or rear brake cooling, not much need for those intakes.

You have the first GK's, 03 & 04. Bubbles on the headlight clear cover.
You have the GK FL (facelift), 05 & 06. Same size headlights, but a nice smooth curve on the headlight clear cover.
You can can just swap headlights between GK & GK FL's, simple bolt in although there may be a minor wiring change.
Then you have the GK FL2. Different design headlight which also means different hood, front fenders and bumper cover. There are also other body changes.
95% of parts fit any year except some body parts.
There should be a label on the open edge of the drivers door with the month and year build date. In the US, there is also an emissions label under the hood stating what year standards it was built to.
This site also has a VIN decoder to tell you more as the car was built.

In case anyone else finds this thread, build date can be important on some parts. Example, a 2004 Tib can have 2 different E-brake cable designs. Late '04 is like an '05, early '04 is like a '03. The wheel end is different and yes, there is a thread about it since I posted in it years ago.

You have a 2007 or 2008 based on the fenders, hood and headlights enclosures. The manufacturer date might be in 2006 but your model will be 2007 minimum.

No those rear gills are not factory. Some aftermarket double sided 3M tape on mod.

AKA, FL2 as discussed earlier in this thread.
Curious, what are the intakes made of? Steel should hold a magnet, could be aluminum, plastic or FRP if a magnet falls off.
