Interesting, so who prints the window sticker, JLR or the dealer?

 

Can you buy a right and left snorkel?

 

New Defender Mods makes them custom apparently. Not seen a pair of snorkels on a V8 but no reason they can't drill into left and right fenders to fit them.
I've only seen their SS snorkel on one of their own I believe. No doubt there are a few snorkels kicking about in Australia. Left side only of course. Not seen any in the states.

I've yet to see any other snorkels on the market and in production for the Defender.

The OEM RAI applicable for all trims except the V8 have to be on the left side only for obvious reasons.
