that box is called the air box, its where you engine breathes in its air. you say its leaking oil? these boxes are normally a bit oily but only really surface oil. If you can actually see liquid oil you have a problem with your petrol shut off. When the bike isnt running petrol will leak into the engine through the piston. When you start the bike all the petrol mixed with the engine oil will be pumped back into the air box. also check the level of the engine oil, if too much has been put in there then that can also be pumped back into the air box. If the petrol and oil has been mixing you must change the oil as petrol thins the oil and your bike could catch fire, the engine wear will be really bad.

Stock plug is NGK CR9E, but Denso Irridium IU27 is best. Cost more but better economy and starting.
Any manufacturer will have the equivalent NGK plug for your bike on their chart, with two or three types for your preferred riding style.
