Will increasing the number of voluntary payments increase my pension?

I've just received notification that I have 6 qualifying years of NIC and need to pay 4 (class 2) in order to claim for a state pension from abroad. My question is - can I pay more than that and continue to pay (for another 3 years from now) until I reach pension age. And, will this increase my pension payment when I retire? Or, will it make no difference to the final pension amount. Thank you in advance.
