I got the code to change plugs - I did this on 2006 odyssey and recall it was about 1 hour job and not too easy (only 1 hurt knuckle) so I figure I will do this one too (I think the dealer wants over $300 for this?). I will not buy plugs from Amazon because too many people say too many sellers sell fake ones - so I looked online for replacements. I found on Rockauto that the OEM iridium plugs are about $12.50 each (about half of what Autozone / Advance Auto charges locally). However, Rockauto is selling the Ruthinium plug for only about $8 each. I thought they were supposed to be more expensive?? I am fine sticking with OEM plugs for the $12, but if the supposedly more expensive plugs that are now used by the Manufacturer are less ... would it make sense to just use them? I don't care if they last 200k vs 100k (probably will not have this for another 100k miles anyway) but is there any risk to performance by going with Ruthenium? Any opinions?
