You can get a torque wrench at Harbor freight for less than $20 and if you are a do-it-yourself person you will need this for every mechanical job you do. Lawn equipment,automobiles , or anything that uses machined parts you will always need a torque wrench. They will last a lifetime if you clean it and zero it after every job.

Great instructions! I was able to change them pretty quickly.

JOEL DENNIS - Contestar

First rule of thumb when changing spark plugs is to do it when the engine is cold. If you don't have a torque wrench it's ok, you can still tighten them properly. Easiest thing to do is put the new plug in the spark plug socket, attach the extension (8 or 10 in. is perfect) but not the ratchet. Thread the plug in until it is snug, then attach the ratchet to tighten. Most spark plug manufacturers put on the box (especially NGK) how much to tighten. Usually if the plug has no gasket, tighten 1/16 to 1/8 of a turn. If it has a gasket, tighten 1/2 to 2/3 of a turn. For an '05 Accord 4 cyl. they have a gasket.

I appreciate the thorough and precise instructions. I would add using anti-seize on new plug threads.

On an '05 Accord, are there any wires that need to be replaced at a regular interval?
