Hate to disappoint,.. but it's gonna' run about the same...
Hopefully it lasts longer,.. but I don't know..

"Wonder plugs",.. are snake oil...

You are still burning the same amount of fuel,.. you'll still have the same HP's and same mpg's...

Don't feel bad...  I bought 8 "Super-Duper" plugs once...
That one really hurt!...   ...

In my impetious youth I bought some expensive spark plugs.......the advertising and claims lured me in.  I tried the dual and quadruple electrodes, surface gap plugs, etc.  The end result is that if they were so great for performance and mileage - the factories would use them as part of their expensive research to get better performance and mileage.

There has been a great improvements in plugs when they started making the thin electrodes out of exotic metals - this makes the plugs last longer.  The old standard plugs would get rounded off electrodes and that made it harder for the plug to spark properly.

For me.....fancy plugs do very little in a primitive engine like the Suzuki S40.  Get a a factory recommended plug and your engine will run just fine.
