Assuming your engine code is 1MZ-FE you want dual tipped platinum plugs. There should be a picture of what the plug looks like on the underside of your hood. It is a multi ground plug. OEM replacement is Denso part PK20. Iridium plugs are a waste if you are staying n/a, but if a supercharger is in your future you are gonna want to consider a plug that give you a cooler spark like Denso Iridiums (IK22 I believe). Whatever you get, use denso, or ngk. Bosch plugs are for german cars.
