I bought from here to make sure the plug was an original NGK and not a fake item as you are likely to get from online auction sites.
Plug is a good quality item and makes the Pegaso 660, Yamaha xt660z and others run slightly better. Main reason for fitting is the very long service life.
Recommended.

My spark plugs were about due to be changed (2002 Honda cb500) so I took advantage of an offer on these NGK iridium plugs. They are meant to be more efficient and longer lasting, the bike does seem more responsive since fitting them.

More miles, a cleaner burn...

I've been using Iridium plugs in cars and bikes for decades now, once I've changed a vehicle over to them, I've never then needed to change the plugs again in my ownership, despite doing thousands of miles! Copper is great, but it's soft, so over time the gap widens and if not run at the right temperature, the metal fouls, not so with Iridiums, brilliant.
