    ...and buy from a reputable source. Counterfeit plugs are a thing.

    I'd pull a couple of plugs and see if they are actually worn. You should not be having issues at 65K. Toyota does not cut their maintenance schedules that close to failure. I'd bet you have something else going on.

    Winter gas is more likely the culprit. I changed my plugs at 101k. They were still okay to use. Iridium goes a long way.

    Old thread, but you should. Most are loose from the factory especially the passenger side. Stick with oem plugs.
