Are you asking about the difference between standard nickel plugs and iridium plugs or between NGK's iridiums and Denso's Iridiums?

x2 on that one QuinC.
Spark plugs are something that most of us probably take for granted (I am def one of those riders) and do not see the "gain" in purchasing a more expensive replacement.
So Sparkplugs.com, what are the differences between nickel and iridium (besides $$)? And what about NGK vs. Denso?

Excellent questions. We wrote up a thread on this a few weeks ago: http://www.cbrforum.com/m_200295/mpage_1/key_/tm.htm#200295
It has detailed technical information on spark plugs and answers a lot of common questions, such as what the difference is between nickel plugs and iridium.
In regards to the NGK vs. Denso question: In summary, you'll learn on that technical thread that the main performance gain from iridium plugs, doesn't actually come from the iridium, its the fine wire center electrode. The thinner the center electrode=less voltage required=fewer misfires=higher mileage and more horsepower.
NGK's iridiums have a .7mm center electrode. Denso's are .4mm. - Its up to you if the extra .3mm is worth the price difference. Other than that, they are both excellent plugs with excellent quality.

Thanks for the input/assistance.
Correct me if I am wrong; don't our bikes (well at least my F4i) come with iridium plugs already? I was just looking at the service manual and it listed two replacement part numbers (NGK IMR9A-9H and Denso IUH27D) and they're both iridium plugs. So what's with the "standard nickel" plug you mentioned? Why would I want to put 4 of those in? Just to save a few bucks?
Finally, once I put my Power Commander in this spring - would it be beneficial to change the plugs? I currently have about 13,000 miles on the bike/plugs so I don't think there would be a problem leaving them in there (unless they're NOT iridium).
Thanks again,
Joe

If your bike comes with iridium plugs OE, that's great, that means the manufacturer is giving you the best plugs you can get. Standard nickel plugs (also incorrectly referred to as "copper" plugs) are your basic $.99-$2 spark plugs you can pick up at your local autozone - it is what most vehicle manufacturers install OE because they are least expensive. Iridium's are the high performance plugs, only some manufacturers install these OE, but usually, you'd install them aftermarket if you want optimum performance.
Standard nickel plugs will last, on average, around 30k miles. Iridiums should last between 60k-80k on an unaltered motor. You'll want to take the plugs out about every 30k miles or so, check the gap, regap if necesary, and make sure everything is running ok. Otherwise, you've got quite a ways to go before your plugs should need to be changed.

I've bought from you guys a couple times in the past.....you have an excellent site and I felt the turn around on orders was quick.
It likely varies with engine/combustion chamber designs, but on CR9E equiped bikes (my assorted Kawi's), I've found measurable gains from CR9EK's (1-2hp, as measured against a fresh CR9E). Yamaha switched to this plug in the early 2000's. Another forum I am on, a guy is going to throw IX's into the mix and test.

That's interesting...How long are the CR9EK's lasting you in comparison to the CR9E?

If I keep a bike long enough I'll let you know.....
I change plugs with every valve adjustment as it such a pain to do them at a different interval...so 5-7K...Can't say as I've ever "worn out" a plug in a bike to the point of re-gapping or replacement yet...probably just what you like to hear....HA.
Ever have problems substituting a denso plug in something that was NGK from the factory? In my experience, anything that came from the factory with NGK won't run right on anything else....from my weed-eater to my sleds/bikes/cars. Denso is no small company, so I am sure they make quality stuff as well.
