Hey everyone. I have a 99 ES300 and I am looking to replace the spark plugs. What kind of plugs are you using?

godzillatreat,

I presently have Bosch Platinums in three vehicles and they all run flawlessly. I've been using them in all of my vehicles, except my antiques, for the last 20 years or more. Not one has ever failed. By the same token, Bosch makes three models of platinum plugs,I believe. I've only used their least expensive, single electrode version.

Thank you both for the response. I will do a little more homework about both plugs.

I also use bosch, single electrode plugs. Whatever brand you decide on, make sure that you gap the plugs!

Denso. In general, Denso is a good brand to use in japan cars. If you notice, the larger fuses thet they come stock with are made by Denso.
