It is good to know that the plugs are good past the 100K mark. Has anyone used the Denso plugs? I heard you should use either NGK or Denso platinum's. How much are they selling for in stores. My dealer sells them for $25 each and I would obviously not buy them there.

The platinum plugs started going in 4cyl(not sure about the 6 cyl) engines in 2000. So your 99 may still have the regular NGK or Denso plugs which are $2 each at AZ or AA. The platimum plugs run $10-12 at the aforementioned stores. You can certainly upgrade your plugs if you still have the regular ones in there. The autoparts stores also sell plat. "tipped" plugs for around $3 each but those are NOT the 100k full plat. plugs. Some people have confused the two.

I think the iridium(sp) plugs started being used in the 03 and up Accords.

SatinSilver:

Will I be able to tell if I have the regular NGK plugs or the full platinum plugs by removing them and taking a look? I have never removed spark plugs before but I assume there would be some distinguishing characteristics between the two that I could tell which is which.

Possibly...an easier way would be to check the back of your owners manual for the part number. The p/n for the 30k NGK plugs is ZFR5F-11. Do you still have the originals in there? If you had the timing belt package done at the dealer sometimes they will replace the plugs. So you may want to check your invoice to see if they were changed.

I replaced mine at 50k. I wasnt so worried about the quality of the plug, more about the ability to turn them out in another few years. That idea is probably not warranted, but I have seen a few heads up on work benches that have been ruined by owners that have done crazy things getting a sparkplug out.

I believe I do still have the originals in there. I bought the car with 61,000 miles on it so I would think they would still be the factory plugs. I did have the timing belt service done but I did not have them do the plugs though (seems like something I could do myself and save some money.) They wanted to charge $25 per plug and 1 hour labor (my guess $75). 225 for spark plugs?! No thank you!

I will check my owners manual and see what type plugs they are. Thanks for the plug p/n. Anyone have any first hand horror stories of getting the plugs out? I have heard they can be a pain sometimes.

The plugs may have been replaced at 30k, 60k or both since thats when the recommended replacement interval is. If your going to keep the car awhile I'd upgrade the plugs to the full plat.($10-12) or the plat. tipped($3) NGK's over the $2 plugs. The service advisor at the dealer said it was easy changing the plugs...at least on the 4cyl.

So I bought new plugs at AA. Asked the guy at AA if he knows of any good indy shops around. He recommended this mom and pop shop down the st. The indy shop did it for $4 per plug = $16 plus cost of plugs.

Any tips on getting the spark plugs out of the rear cylinder bank? What kind of tools do I need besdies the following (per the Accord Hayne's manual):

1.) Spark plug socket - has speciall padding on inside of socket to protect spark plug

2.) Torque wrench

3.) Ratchet

4.) Extension - probably a good idea to get out rear spark plugs on rear cylinder bank.

5.) Spark plug gap gauge

6.) Snug-fitting rubber hose - will save time and prevent damaged threads when installing spark plugs.

Well, just to add some personal info.
My wife drove her 2003 Civic 305k miles, and never changed her spark plugs.
Honestly, i'm sure she never changed lots of things (belts, fluids, etc ) but it was running great, until it was totaled. (by the time I met her, she had already put on 200k, so I didn't bother to manage upkeep. With her/our 08 Accord, eh that will change.)

So, I would definitely suggest the suggested interval, or sooner if you wish.

Below are pictures of my six spark plugs after approximately 110,000 miles. I think they look pretty good.
