2011 Busa plugs

[Kaptain Kanji]

From what I read, the 2011 Busa is going to come stock with Iridium spark plugs.!!
Great for performance but not so good for gas mileage.

I run denso iridium iu27 and have never had any problems related to the sparkplugs. On average I get around 44 mpg and have seen 50 mpg highway.???

OK, lets hope you're right.!!
I know it made a BIG difference on the Harley for some reason.

If I'm not mistaken my 08 has iridiums. Ten thousand miles and haven't had a problem but I'm goin back with a cheaper plug when I replace them.

Don't Gen II's have Iridium plugs from the factory, or am I making that up?
