My 2008 Sienna LE is 12 years old and has done 130,000 miles and I thought it was about time although the van has always run well. The factory ones I removed were also KYBs (just with a slightly shorter cylinder), they looked and worked like new :(I replaced them with the new Excel-Gs but I think it was a waste of money. Obviously none noticeable changes, too.. I think our roads in Atlanta are very smooth, at least the new ones will last 130,000+ miles :)
