Welcome to the ForumZ!!

for me, i change my oil once a year so that is when i change my plugs, but i also dont have that many miles. plugs are only around 2 bucks each so as far as i am concerned its not gonna hurt anything to change them more often, but i would do it at least once a year, if not more often.

Agreed ^^^^. On my older vehicles, a tune up - plugs, wires, cap and rotor once a year, oil and air filter changes as needed depending on how much I actually drive them.
