There are two options for our cars (Double Platinum plugs with dual electrodes):

Denso 3253 PK20TR11

NGK's cost me about $84 CAD with discount.

Denso's cannot be found locally in Canada.
Denso's cost me about $36 USD in the US shipped so cost wise they are the best and should be equivalent to the NGK's.
I believe the Denso was OEM from the factory.
