According to the Haynes manual it says to torque: 2001 to 2005 at 15 Ft-lbs. Going to 21 ft lbs you are over torquing it. Just remember a spark plug is not just made for one car. Some have steel heads and some have aluminum heads. Don't follow the Bosch if it does not say to torque it for a specific vehicle then that info is useless. Also I prefer NGK or Denso which are recommended by Toyota. I have used Bosch on a Camry with no problems so as long as you don't have performance problem should be ok.

second to that, i recommend toyota specific spark plugs, you can always ask them for torque specs. 14ft-lbs. check always the gaps, 1.0-1.1mm, max 1.3mm before installing.

I ended up going with the Denso plugs. Got them for $5.50 a piece. On the back of the box it says to turn it 1/16. Thanks for replying.

Even though they come pre-gapped still check them?

My SK20R11 plugs came with a 1 mm gap. I opened them up to 1.1 mm as specified in the manual. Torqued them to 15 lb-ft.
