Best Spark plugs for a Hayabusa
This item works well on my 2001 Hayabusa. The gap size was also on point. The engine is way smoother now.

Will work for 06-15 Yamaha FZ1
These will 100% work on a 2007 Yamaha FZ1, you just have to take off the top of the spark plug (it screws off) and just make sure to gap them correctly.
