WAY TOO MUCH! I bought high quality sparkplugs (DENSO IKH20) @ www.sparkplugsauto.com for $50. Also bought Mobil-1 75w-90 synthetic gear lube 6L for about $66. Enough Mobil 1 5w-30 motor oil for about $35ish @ Walmart. Toyota charges about $20 for all of the gaskets and oil filter. Then grease to lube driveshaft zerk fittings. Am I missing anything? If you have all of the tools, do it yourself. Or you could buy all the tools and still be under $600.
