To be 100% sure, check your owners manual or the internet. You may also want to search this site for info on the Iridium plugs.

Yes they will work.

Yep. they'll work as it's the same plugs I put in mine...

For those of you that have used them, are they worth the extra money? thoughts?

I did some research awhile back on the different types of spark plugs. From what I gathered was that between the three types (standard, platinum and iridium) the standard type had the better conductor at the tip, causing a better spark thereby burning fuel more efficiently. It's downside was longevity. You will have to change the plugs much more frequently. Platinum has a much longer life than standard plugs but the material used in the tip is an alloy (combined metals) with a much greater resistance value. In other words, less spark at the tip. Iridium plugs are a different alloy with lower resistance than platinum plugs (hence greater spark) but not as low as a standard plug. Iridium plugs are said to have the same life span as platinum plugs. (2 to 3 times the life of standard plugs) From what I've read the average person is not going to notice any appreciable difference in performance in any of the different types.

On the other hand... I've not found a whole lot of reviews on the new Pulstar plugs we see advertised on the forum. They look promising but are very expensive.

Thanks for the information

What I noticed was faster cold weather starts. I can start bike and after couple of minutes take it off of choke. I never could do that with the regular NGK plugs. I had to run bike at least 5 to 8 minutes before moving the lever to no choke or enrichment.

To me it was worth it.

Better cold starting from my experience but no performance gain. With a vtwin with carbs in colder climate/riding, I'd say go for it but $28 vs $10 in warmer climates, nah.

I don't have any problems cold starting my Shadow with standard NGK plugs using the choke the way it's meant to be used. And at a cost of just over $2 per plug, I see no reason to go for the fancy stuff. If you're going to be riding in temps < 30*F then go to a hotter plug.

I agree with Eagle...Standard plugs choke out 30 seconds choke in..once the bike has fired it is down to fuel mixture and feed.. the spark keeps going.
