Thanks for that info, Pepe! BTW, I think the note about stock heat range got misplaced on your earlier post?

Thanks again, I misread in "Since the car comes with NGKs PFR7G-11, 8 (or 24 in Denso) would be perfect for performance driving" that it came with 24 in Denso. My bad. Thanks for the info.

 

Although my stock spark plugs are still ok at 30000miles of hard drivin', I wanted to try iridium spark plugs based on just hearing good things about them despite the cost. However this is still relatively very cheap to try out on our car and I believe it is worth a try and not having a feeling that your money is wasted. I am sorry that I cannot give you any scientific data or measured performance figure but only words from my mouth. It would be great when Pepe report back to us with dyno test when he install his.
I cannot tell you that this has given my car to perform better noticeably, but like I said it looks like my mileage have improved.
But don't take my words for it like gospel, I will share with you after more driving.
That group-buy price on Denso Iridium sounds very good. But as usual if you want hassel free and trusty product, pay bit more and go with Spoon packaged Denso plugs. Their product is usually just plug and play.

FYI, Denso recommends IK22s for the S2000. IK24 and above are considered racing plugs and considerably more expensive to get. The reason why Spoon sells IK24 and IK27s are for racing and autoX uses (That's what their website says). They are pre-gapped. The group buy ends this Sunday.
