Here are mine. Look pretty healthy i think.

 

Could someone please tell me what sparkplugs they would recommend for better performance on a stock 2002 honda s2000 with 110k miles. I want something reliable and strong but im new to this car and have no clue what to look for in terms of parts ie. better overall lifespan of the car.

Thank you

Also if you could please tell me what brands of fluids you use for oil, differential, trans. etc.

 

All you have to do is look on the forums; all of your questions have been identified, discussed, and quantified ad nauseam. It is all here for the taking.

 

I know that this thread has been around for a long time. As a "new" S owner, I find many of the DYI's posted on this forum very helpful in learning some of the tricks in maintaining this car.

I did find that it is much easier to remove the coil connectors if you start with #4 (closest to the firewall moving forward), stand on the driver-side and use your left hand to press the release tabs. Once the #4 coil is removed, #3 is much easier, ditto with #2 & #1.

 

I always find it easier to remove the #1 coil and work towards #4 , I guess you can do it either way. I pop up the coil first then I remove each coil clip once the coil is popped up. One trick I do use is to use a small flathead screwdriver to remove the coil clip as they can be stuck onto the coil a bit tight with almost suction like force, and I don't want to tug on the electrical clip as it may break. I squeeze the sides of the electrical clip, then I insert a small flathead screwdriver between the end of the clip and coil, and give the screwdriver a 90 degree twist and the clip will slide off easily.

 

Just changed mine, any thoughts on the condition of the old plugs?

 

take a look

 

My car has reached 10 years and a bit over 40k miles, asked in dealer for new plugs, none in stock require ordered in, master tech reckons not to bother should be good for another 10 / 15k Miles. What do you guys think? Tech didn’t’ look at the plugs, was just his opinion whilst chatting at the parts desk.

 

I replaced my plugs at about 40K miles (and 10 years) only because I had them out while doing the valve clearance check as it made it easier to rotate the engine and the plugs are cheap and available everywhere I've looked including . (Plug removal is NOT necessary to rotate the engine but does make it easier.) In my packrat mode I saved the OEM plugs and they look fine. And I have a new set of plugs sitting on my desk "just 'cuz" for my next valve adjustment.

You can get NGK Ruthenium plugs for about $30 shipped, from Rock Auto(google 5% discount codes). These are a recent release and I installed them into my NA S2000(they don't have heat 8/9 for S2000, yet). I have a set of used(only 500 miles on them) NGK Irdium IX heat 7's for sale too, those are in my for sale thread.
