Replace plugs on Toyota Tundra 2005?

I just replaced the plugs on my 2005 tundra 4.7 v8. they are easy. their is so much room to work with. But do use the genuine Toyota spark plugs. "Do not use aftermarket plugs" i garauntee if you use the aftermarket plugs, you will wreak havoc. the heat range is too high on the aftermarket plugs, and therefore will burn holes in the ignition wires. check eBay for Toyota plugs or your local Toyota dealer.
