Help on spark plugs!

We are trying to find the equivalent for R6701-8 NGK spark plug which we are currently running in our TT 300Z, evidently these plugs are not known in Australia. Does anyone know the equivalent plug to use? We have already looked on the NGK website and came up blank. The car is currently set up for sprints and hillclimbs.

 

Have you tried......>>

Speaking to anyone at NGK? the Australian website http://www.ngk.com.au/ has contact details including phone numbers in most states and in dealings I've had with them in the past they were most helpful.
