xu7 160cc plugs

Can anyone suggest the plugs to use in a xu7 1600cc engine

What actually is it? As an xu7 is usually 1800cc. A “1600cc” is usually an xu5. Standard engine? Modified? 8v or 16v?

It`s a xu7 with 1600 internals to be used for tarmac

8v?   depends on compression ratio but I'd be looking at Bcpr7es, or change up to 8 if you need to, though they foul up much easier so you need a good cold start map.

16v  12:1 comp ratio

Still 7’s.
