Joey didn't really advise against colder plugs. He just said he didn't see any real gains from them. I've used colder plugs w/good results in my other cars, but I'm new to s2ks,so i went along w/his recommendation to stick w/stock heat range plugs.

 

Here's a link to the S2000 maintenance schedule.

If you are thinking about it, or don't remember when they were last changed, I would change it for the piece of mind.

 

Mine were changed at around 75k on my 06 AP2 showing no major issues. I used the standard NGK plugs from Honda when replacing. I am not sure there would be any benefit changing them out more often than 50k-75k miles.

 

I ordered the OEM NGK's just for safe measure. Was cheap only $10 each on Amazon.

 

So I changed my plugs. My car is an 05 with 28k miles. These are original plugs to my knowledge.
My car actually had denso pk22pr-l11s in there.

I dont have a feeler/gap gauge at the moment but it looks like the electrode is already worn down.





I went ahead and replaced them with NGK PFR7G-11S Laser Platinums.

 

so what is the consensus from those that have changed? I read somewhere that OEM ngk are not the same as aftermarket?

 

ngk laser platinum plugs? sounds fancy. lol what's the diff between those & regular platinums?

be careful using a gap tool & feeler gauge. you can damage the electrode if you treat it like a gorilla.

i didnt get a good look at the electrodes when joey changed my plugs, but mine had a lot more buildup than yours, but i have 75k on my car. it was a night and day diff after joey & ben changed my plugs and did the valve adjustment. car runs ultra smooth & STRONG! i wouldn't run plugs past 75k. they might not NEED to be changed, but w/all the crappy gas out there, i'd rather spend a few $$ to change them early. pay now or pay more later.

 

I have put 100k miles on NGK Iridium plugs twice. Both times the center electrode looked the same as a new plug, no wear. On the first set the ground electrode was ate up(standard ground electrode) and the gap was over 1/2 wider than what it should have been. On the second set of Iridium plugs I bought the plugs with the Platinum tip on the ground electrode and after 100k miles the gap had opened up only .004, still changed them out for new plugs though.

"All that crappy gas?" - you don't get crappy gas in Cali. The State regulations on gasoline mean that even "government gas" that you get at non-tier1 has stations are up there with the best of them. The cheaper brands just don't have the same additive/detergent packages that the Chevrons and Shells etc have...

Now if you lived outside of Californian then you might have a point but in the Golden State you get some of the best gas in the world with regards to emmisions and crud buildup or lack thereof. The only issue is that we only get pisswank 91 octane.

 

^This. We don't get "crappy" gas in California. We just don't get 93 or higher octane like some other states do. If you want a higher octane, just mix in the appropriate amount of 100 octane.
