After disassembly

If you have ever wondered whats involved in replacing spark plugs in a 2005 Toyota Sienna well here you go.  As you can see you have to remove a fair amount to even get at the rear spark plugs. Replacing the front spark plugs is a piece of cake! The rear spark plugs not so much. If you get a quote to replace spark plugs in your Toyota Sienna you can expect to pay for 4.2 hours in labor time alone. Then you will have to factor in the cost of 6 iridium tipped spark plugs. Iridium tipped spark plugs usually should be replaced around 110-120 k miles or so.
