Look in the FAQ section at the bottom there is a link to Jackson Racing and they sell the NGK's I bought them for under $20 I also have a d16y8.

Running colder plugs helps reduce the chances of detonation. I just run a set of oem replacement plugs re gapped and they work fine for me with no problems.
