Iridium Plugs?

Recommended Posts

Are these worth dropping 2x the money on, or do they give an actual performance increase?

Thanks,

I do not know about a preformance increase...? I do know that in my wr250 they resist fowling like crazy. I put in a regular ngk and it fowled in about 3 weeks time. I put in an iridium and have had it in there for right at 1 1/2 years now and it has not fowled yet............ :cry:

Yep, since changing to Iridiums, i've noticed they last twice as long, and resist fouling better than the stockers. Ran them in my old street bike, and noticed crisper response on that bike, but didn't notice any difference in my 426. They might cost double initially, but if you only have to change them half as often as stockers..... :)
