Stick with stock, you are wasting money.

That's about what I paid. If you go with NGK iridium, you can get them for much cheaper...

Although you can't lose with stockers, sometimes I just like to try things if it'll make a small improvment. I don't mind swapping them out in 30k miles because I only rack up 10-12k miles per year.

Then you would be better off getting NGK copper plugs.

They do wonders for many different Honda cars and they are stock on the Toyota Matrix, I believe. I just installed some on my friend's SI and we couldn't feel any power gains. The car ran smoother, but it may have been since the plugs were new compared to his 20K mile used plugs. I using the NGK Platinum and until someone can dyno verify the gains from fresh NGK Platinum to NGK Iridium to Denso Iridium, I'll just stick with the factory recommended plugs.

I tried them for a week on my 2000 max. didnt really notice anything. for some reason i felt a slight improvement in fourth but thats it. If you really want to try them, I will give mine $25 shipped. not sure if they will fit though

I dyno tested them on an extremely modified Honda VTEC motor and noticed absolutely NO gains. I also have seen two failures with iridium plugs so I no longer use them at all. Stick with stock unless you're running turbo or SC in which case I suggest a colder heat range.
