Ignition coils and spark plugs

150 per hour is a pretty high labor rate. The shop manual for your vehicles calls for 2 hours to replace plugs, 0.5 hours for coil, combined it would be little more than two hours for labor, so 300-350, and that's a high rate mind you. Add that to the parts cost and see how much this dealer is sticking it to you.

Yes, I agree. Thank you

Don't know how much they were charging you in labor to do the job, but 150. an hour seems high. Should take 2 hours or a bit more if they are seized. So that would be 300.$ And to put the Iridium Platinum Plugs that it calls for runs $10-$12. A piece , but does depend on where you live. ( unless they put in Autolites in but I doubt they would put them in) and for good coils that aren't even factory your looking at 60-125 a piece have no idea what OEM ones cost. But you don't want to put junk parts in or you'll be doing the job again, sooner . But even with that it seems high. We just did Spark plugs and one coil, labor was 96.50 spark plugs 63. And coil 99$

I have been quoted a similar price in 2022 by both a Toyota dealership and independent shops. The problem is that the 2GR-FE V6 engines sit sideways, with three spark plugs situated up against the firewall (on Avalon, Camry, Highlander, etc.). To do the job right, you have to remove wiper blades, wiper motor, cowl, air intake plenum, and the list goes on. It is labor intensive AND if you do not route all the various hoses correctly, you can end up with major engine issues. While you've got the engine 1/4 disassembled, you might as well replace the gasket on the air intake plenum and the gasket on the throttle body. These gaskets are affordable, but make sure you get the right (colored) one. You will have already done the labor for these gaskets on your way to reaching the back three plugs and coils. Given the difficulty of replacing the back three spark plugs, you might as well spend the extra $125 per ignition coil and replace all three back coils ($375 total). The ignition coils are good for 100,000 miles, but CAN last the "life of the vehicle". Replacing all six coils with OEM is $750. Can you get aftermarket ignition coils? Sure. But you will likely end up replacing them after 25k to 75k miles, and you'd better hope that it is not one of the back three coils or else the labor and risk (route those hoses correctly put everything else back at proper torque specs). The front three plugs and coils are child's play compared the back coils. YouTube has videos by a certified Toyota mechanic and various "shade tree mechanics" that demonstrate how laborious and risky (putting everything back to specifications - house and harness and torque) this simple-sounding job really is.
