just found this bit of info,it seems i have the wrong plugs then ? ------------------------------------------------------------------------------- NGK BKR6EP-11 was the plug they came with from the factory. When Toyota crossed over to Denso it became PK20R11 Both brands are platinum type. Toyota now use Denso plugs. -------------------------------------------------------------------------- my current plugs are tan and look bang on,because of this should i just stick with what i have but renew to the same identical ones ?
