Toyota Repair: Spark plugs, camary, iridium

Question
I have a 2002 Camary LE 4 cyclinder. How hard is it to change the spark plugs? What type should I use as replacement?

Answer
It's not hard at all,remove the black engine cover, remove coil packs by taking off the 10 mm bolts, disconnect the connectors and pull the coils out of the tubes, you need a 5/8" spark plug socket with a 8" extension and a ratchet to remove and replace them. Use the OEM spark plugs, contact the dealer's parts department, they are either platinum or iridium tipped, if platinum they are replaced every  60k miles if iridium the are replaced at 90k miles.
