Denso Iridium Racing Spark Plugs





#1
Hi Busa Boys and Girls!

Just looking for new sparkplugs to my 1999 Hayabusa and GSXR 1000 K8 and saw one thing, the Denso Iridium Racing spark plugs.
Why are these Iridium spark plugs so much more expensive than let's say Denso Iridium Power or NGK Laser Iridium? Even on eBay.

I tried to search both YouTube and Google for some reviews but didn't find any review that compares these plugs to other iridium plugs.

Have you guys any experience with these?

My bikes are Street bikes and I do track days sometimes so no Turbo or NOS.

Best Regards
Marko
