Your engine has a wasted-spark ignition system that requires dual ground electrodes. Toyota does not recommend non-platinum plugs for your car, so I would spend the extra cash and get what Toyota specifies, which is: Denso PK20TR11 (also sold as Toyota 90919-01194) or NGK BKR6EKPB11 I'm told that some aftermarket ND plugs come with screw-cap tops, even if they are otherwise identical to OEM Toyota. So check for that if buying ND plugs in the aftermarket. The screw-caps can come loose, and cause problems with arcing and damage. OEM Toyota ND plugs have solid tops. -- Tegger

Wow thanks for the research and the sites! Just wondering, what are the drawbacks going for the $3 plugs? Would I get superior mileage going for the more expensive plugs? Or is there the risk that the metal electrode will fall off? ================ I can tell you that based on the recent experience of an acquaintance, you do NOT want the electrode to fall off. It's interesting, sort of like having your shirt catch fire. That sort of interesting.

How often do you change plugs? For you it's been 11 years since new--is it worth going for the cheapies?

My guess is that the laser spark plugs are a marketing gimmick, much like Angus beef and new improved Tide. If your electrode falls off, it's likely due to a manufacturing defect. I've never heard of this happening. Worry instead of an asteroid crashing into the Earth and ending all human life.
