Good evening to all.
I own a '06 uni with a stock spark plug and over the years have been changing with the stock ones only.
But,
I Recently came across the twin headed spark plug from Bosch and im a curious to know that how far is this Spark plug performance oriented, is it worth fitting on my bike ?
Is it a direct fit ?
Will i experience changes after its installation ?
Or is there some other spark plug anyone of u can recommend for my uni ?

Thanking ya'll in anticipation.
