Comments about NGK Nickel Spark Plug (CR7HSA):
OEM replacement for Buddy 170i scooter. It fires without fail (with one cylinder - you'd know if it didn't)and lasts more than 10,000 miles. I could have gone further on the same NGK plug it replaced, but thought I'd give my scooter a treat. There are cheaper plugs, but none perform as reliably.
