Spark Plug?

[Vust123]

Putting a new set of spark plugs and I was just looking around and found these, any one know anything about them? Are they worth it?PERFORMANCE SPARK PLUG Yamaha FZ1 FZ1000 FZ6 FZR600R FZS1000 Mountain Mountain | eBay

Just stick with ngk

I recommend the standard, regular copper NGK.

Just don't get sucked into buying the Iridiums - a lot more expensive and they are less economical.

Cheers,
