the platinum plugs is a step down from the original iridiums that our RAV's came with. unless your plugs are worn or fouled up from maybe bad gas or driving a lot thru abnormal conditions, it would be a waste of money to replace them now. stick with Toyota's recommended maintenance schedules and OEM parts.HooH said:I'm thinking about changing the spark plugs on my 01 RAV4. Any suggestions? Hows Bosch's platinum plug or E3 spark plugs? I got 30k on my RAV4.
