Probably. But be careful what ram you buy for your Mac. I made the mistake of going "budget" last year and it wasn't pretty. Kernel panics, hangs, the works - on a brand new i7 MBP. Turned out to be the Ram. That was also kingston stuff.
Saying that Kingston is a known manufacturer and it apparently those sticks are for Apple. It will fit your machine, any good - depends, wait and see.
Otherwise buy from someone like Crucial, their ram is all guaranteed to work and with full warranty etc.
