Does supercharger really require spark plug replacement every 30K miles?

If in doubt you could check your plugs to see how they look, that should give some indication.
I use also a heat range colder plugs (6) on my car, and my plugs look very good, so guess it will be alright.
You could also keep your plugs and add the twin-screw, that way you will have the right heat range

And... do them one at a time. That way you don't forget which wire goes to which plug. Many years ago I made the mistake of pulling off all of the wires and replacing all of the plugs at once (on a different car). That was before the internet, and figuring out which wire went where took forever since I couldn't drive to the auto shop or library to look it up. Some lessons are never forgotten.

Jaguar OEM plugs
Just pulled the work sheet from the dealer. Fitted the following plugs: C2A 1535
to my 2001 XKR 4.0L at 68,000 miles. Only done 73,000 so no need to change. Looking on the web these plugs are Iridium Spark Plug - C2A1535 - Genuine Jaguar at www.rimmerbros.co.uk.
They had previously fitted AJ8 4575 plugs at 43,000 (so a 30K interval) - these also show up as Iridium so I am guessing likely same plugs with updated part numbers
I presume no great difference with NGK or Denso. Likely made by them anyway and rebadged.
