Yung Rav4 & Camry (and most Lexus vehicles) naka Denso Iridiums (OE) na... according to the manual it is good for 100K km... according to the manual in the US and the Denso Iridium website it is good up to 120K miles (that is 192K km). Several Rav4 owners abroad have reported of the minimal wear & tear of their iridiums ever after logging between 60-135K miles on their vehicles.
Btw, stick to the OE spark plugs on your vehicle... spark plug upgrades are a costly hit-and-miss experiment.
