Can someone recommend the right socket for removing and installing the spark plugs? I have the right socket but can't find an adaptor or extension to reach to the deep hole where the spark plug is located.

Thanks

Replace with the engine cold. This was not too much of an issue with older iron blocks. A dab of antiseize to the plug threads (3 threads away from the tip end). Dielectric grease on the rubber boot. These help future removal.

Use NGK Iridiums. (-IX or -Laser). Good stuff. I'd stay away from Denso plugs, not even Toyota's racing team wants them (they used Bosch).

Just a simple question..... Why do you want to change plugs? The reason I ask is that I have a '97 Camry 4 cyl. with 142,000 miles on the clock. I bought it as an ex-Hertz rental in 1998. I have changed oil and filter regularly (every 6000-7000 miles) and had the timing belt and water pump changed at about 110,000 miles, but unless the plugs were changed by Hertz in the first year of their ownership, they are the original plugs, as are the wires. The engine runs smoothly, with no misses and no coughs, starts instantly, and so on. I see no reason to change something that appears to be working like new. I'm sure lots of folks would say this is "poor maintenance" but is it?

Evan simpler answer, how about 5 more mpg? The old plugs had 172000+ miles and really looked bad.

If you're referring to my car, it has 142K miles, not 172K. Gas mileage is in line with other Camrys. And since I don't look at them, I couln't care less what they look like.......it's how they operate that matters.
