OS.8 plug, 25% nitro, 40 Celsuis...bad combination?

[flash]

I seem to be getting through plugs at a high rate which is costing a fortune. The last one I had ran one tank in my Sav X4.6 and then died. Usually I get a few tanks before they go. Incidently I am also running a Hyper ST also with the 25% nitro and O.S.8 plugs and the same things seems to be happeing.

I am living in Dubai so the temp in the desert where I run can be 35 to 40C and humid. I guess that cant help.

I need to go back to my LHS to get some more plugs. Should i be using hot plugs, cold plugs or just switch to lower nitro?

I live in Houston Texas, witch has a similar climate to Dubai very hot and humid in the summer time... in the summer i run a cooler plug but its fall and cooler out so i am running an OS#8, i run 30% nitro. But when its warmer outside i have to run rich...

cold plug O.S 5 or R 5 if you like O.S Plugs

Those OS plugs are shorter then regular plugs, they will lower the compression in the engine and it won't perform as well as it could.
