Hi I have a few questions about spark plugs

I might need to replace my spark plugs soon, whats the difference between the NGK Spark Plugs & The Denso Iridium Spark Plugs and which one would you prefer using/buying for longer lasting performance/spark etc.


Where can i get an RVF400 Spark Plug tool?, My Spark Plug Tool won't remove the plugs that are currently in my bike.

I've only ever used NGK, I personally don't see any benefit in using the more expensive iridium plugs. The standard NGK plugs have lasted more than 25,000 km's in my road bike before.

Call me cynical but 'iridium' sounds like marketing BS/spin to me, I doubt there are any real (tangible!) benefits to you and I.... and the standard plugs are pricey enough.

I use a 13mm long (deep) socket on an extension for the plugs, works a treat. I also made a rubber cutout with a hole in it and stuffed it into the socket so it grips the plug better on removal. You can get these sockets from supercheap auto and also decent tool places.

HTH

Thank you very much Cammo!

What sizes are the rvf spark plugs & what is the socket size?

8mm spark plugs, deep 13mm socket size.

thanks man!
