Summary: For 2003 Toyota Sienna 2009-09-19
Comment: I just changed all 6 plugs on my 2003 Sienna at 91K miles. The original plugs are NGK IFR6A11 and still worked. Toyota's service manual says to replace them at 120K but my dealership recommended it during the 90K service. So I thought I should give it a try. Toyota's manual recommends either the NGK or this Denso. There are two Denso replacement; this one is supposed to last 120K miles and the other one is supposed to last 60K. I am glad I bought this one as the replacement of the back 3 plugs is very difficult. It took me about 10 minutes for the front 3 plugs but 2 hours for the back 3. Most time was spent on unscrewing the bolts and plugs as they were very tight and untouched for 6 years and the room for ratchet movement is small. I also bought GearWrench 5/8" swivel magnetic socket (80546) for the job, which turned out to be extremely useful for the back 3 plugs. I immediately felt improvement after the spark plug replacement. The engine runs much smoother and quieter and it reminds me of what I felt when the car was new.

The manual says 60k but I would not wait until then.
