NGK B5HS works great and they are inexpensive or maybe you could try the next range cooler B6HS, but supposedly the Chinese stock plug is equivalent to the hotter B4HS...which I don't agree with....but the stock plug is slightly different than the NGK in construction and electrode tip length.
As a side note: my reckoning says a NGK BR6HIX Iridium plug would fit...not sure how it would perform.
