I'm thinking about changing the spark plugs on my 06 civic. I hear better plugs will produce a more thorough combustion. That being said, does anyone know what the difference if between the models?

ie, whats the difference between IK22 vs IK20 vd IK16 etc...

And what should I be using for my 06 civic? I'm planning to getting a set of 4 off ebay or something.

If your planning to get sparkplugs just go to the dealer or NAPA. You won't be saving much when you include shipping & possible customs fee, etc

go with the ngk's u get from the dealer. copper is best for performance

Your 06 civic probably came stock with NGK platinum plugs. I wouldn't recommending downgrading to copper plugs and i don't know if upgrading to iridium would make much of a difference.

I think you should just stick with the stock plugs (since they're good for over 100k) and spend your money on more useful things like regular oil changes or winter tires.

I went to NAPA and they pretty much said the same thing. My stocks should be NGK which are good enough.
