GZE spark plugs?!

Hi all,
I am looking to change my plugs on my GZE.
Im looking to go copper, and from the search, i could only find this spark plug model number to use: NGK BCPR6EY
Is that the right one?
If not, which is reco. for the GZE?
Is it better off going copper than platinum?
(more frequent changing than spending more money on platinum one?)
Cheers

Thanks for the replies..
How often should platinum plugs be changed?

so i asume its smaller gap so its less prone to pre-ignition?
im running 11.5psi boost (max i get anyway) on 1.1mm plugs as above runs fine. i had .8mm gapping and it would cut out at 5500RPM/6000RPM like a hard redline

Its actually got more to do with difficulty igniting the fuel/air mixture with the soaring combustion pressures at high boost.. It shows up as an ignition miss with the bigger (1.1mm) gaps, and can be quite harsh like a rev limiter. Running the smaller gaps (0.7-0.8mm) makes it easier for the spark to jump the gap, but can slightly affect lower rpm & low boost power.
The only way that you will get around having to run small gaps at high boost is to upgrade your ignition system, like a CDI unit etc.
