What kind of aftermarket plugs you guys running? Do they make those Densol Iridim(sp?) for are bikes?Is that a good plug or just overpriced and overmarketed?

 

ngk has an iridium style plug also, which is what i put in my f4 before i got rid of it, you can cross refernce the denso to the ngk and vice versa, i cant be quite sure but it seemed to help, it uses like 25% less power to create the same amount of spark as regular plugs, which i would think should give u a better response,

 

I replaced my plugs with the stock ones from Honda. The next time I replace them which is coming up soon is I will pull the fuel tank this time what a pain. I can't remember which plugs Honda sells OEM.

 

No. Just less draw on the stator. Marketing...

Replace with OEM honda. Check your manual.

 

I just replaced the plugs in my '99 F4 with OEM honda plugs....this of course was after hitting up every auto parts store in town looking for the NGK and Denso equivalent plugs. NO ONE carries the part numbers you need, your better off just sticking to the OEM plugs in my opinion. You can find them easily online, but why would you want to bother? If your determined though I have both the Denso and NGK part numbers if you want them.
