I just ordered NGK Iridium plugs for my Yami. I have paid up to $12.00 at the dealer. I just paid $8.48 with $4.24 shipping and no tax.
I love these guys www.sparkplugs.com

what does the iridium do for plugs Paul?

Looks like a wash in $?

notice the time of yer post buzz?

No Buzz. Figure it out:

$12.00 x 4 = $48.00 x 7% tax = $51.36 plus gas to get back and forth to the dealer.
VS $38.16 delivered to my door. $13.20 in my pocket.

Craig, the Iridium plugs are hotter firing, don't need to be gapped and last much longer without wear. They will not corrode as fast as copper or even platinum, in a hostile environment
I have run the Iridium plugs since my first boat with a Yami 4 stroke and have never had a fouled plug or any plug problem at all. I consider it very cheap insurance.

so those can be used in automobiles also?

Spark plugs are for girlie engines.

If U have a Napa auto parts near U check them out for price on marine plugs, my plugs were 14 bucks each at boat yard, Napa was 6 and some change, sometimes they had to order them and I would have them by 8AM next morning.....:)

Thanks, good to know.

Damn - I have to start paying attention to threads like this - I've been on the no spark plug train for a long time.
