170S Spark Plugs

[James Allen]

What are the current best practice spark plugs for the 170S engine? I realize the factory book recommends Bosch W175 T1 spark plugs. What are your experiences and recommendations for other spark plugs? Thank you for your replies and responses. jim

Hi Jim,
NGK spark plugs are known worldwide as high-quality spark plugs. I use them and have never had any problems.
In your application the NGK B5HS would be the best choice.
