2003 Highlander info

Just had the wifes Highlander at the dealer to have the plugs changed. 85k Miles on car.They charged $94.00 for the six plugs and 1hr labor $85.00. Plugs were NGK Iridium IFR6A. I asked for the old one back. They seemed to of been burning good. Also we had the timing belt changed. The total cost was $408.00 and 3 hrs labor. The reason I did not change plugs is because of the back 3 under the manifold. Too hard to get to. I can't believe they charged $15.45 for each plug. I'm located in the Boston area and the heat this week is in the 90s with high humidity. The other reason I did not do them. Well just wanted to post some current prices for Toyota service here in Boston.
