When to replace spark plugs?

[d00dle]

already looked @manual. the manual doesn't say to change engine oil every 3 months either (im not sure where people come up with this sh*t. I change mines every 4-5 months).

back 2spark plugs, wonder if I should change em every 6 months or so (basically twice a yr).

I change mine every other oil change, but i check them at each oil change to make sure there good

rite, sound good.

what!!?? Once in ten years may be? Replace plugs every 60K miles. If you have an itch to change things - take them out for inspection and gap measurement every weekend)))

Every 30k miles with copper plugs.

Every 30k miles with copper plugs.

30k is normal. most spark plugs can go 50k+ before they are overgapped or worn out

Yeah, spend the 10 bucks, get ngk platinum plugs and run them for 40-50,000 good miles, the only reason to change them twice a year is if they are not that great to begin with. Honda says 30.000 miles i think for maintenance and i would say that is low if you get high quality plugs. I just bought NGK Laser Platinum plugs haven't put them in yet tho, i am hoping to leaving them in for about 50,000, maybe check them once or twice a year.
