Does anyone make a black OEM decklid spoiler replacement or aftermarket one that bolts on. Don't want any stick on spoilers and I'd rather not wrap it if I can help it, not a fan of wrapping cars.

 

I had the chrome oem lip wrapped and it's indistinguishable from the painted car (mine is black) until you're nose-distance away - and only because the car is a teeny bit shinier than the vinyl.

Other than that, there seem to be a bunch of options on eBay and the like but most of them do not supplant/replace the oem chrome lip.

 

If you are referring to the "real" deck lid spoiler that replaces the chrome trim piece, the odds of finding a new, pre-painted OEM spoiler here in the US is next to impossible. As Rotarymike mentioned, there are a ton of aftermarket options on eBay but none of them, to my knowledge, bolt on like the OEM units. I am in the same boat- patiently waiting for a Coupe spoiler in my obscure paint code to pop up...

For a while, Infiniti was selling unpainted spoilers but apparently those have been discontinued as well.

For reference:
KH3 (Obsidian Black) SEDAN OEM p/n: K6030-1NF7B, ≈$420 from Japan (not including shipping).

 

I've got mine painted with some duplicolor metalcast and with the black and blue paint I've got now it doesn't look bad but at some point I'm going to black it out and the shiny color shift won't work with that. Most spray paint I've tried doesn't stick to chrome well.

 

If you'd rather paint it, I think either Naval Jelly (mild phosphoric acid) or MEK would etch the chrome enough to hold paint. Consult a paint shop though - I've not tried this and the spoiler is plastic.
