Review on Champion 9701 Spark Plug Pack by Scott Matute

I used these spark plugs to replace the stock spark plugs on my 2013 HD Breakout (FXSB). They have improved my overall performance and fuel economy. Recently in South Florida I got 52 mpg after installing these plugs. I typically got between 48 and 50mpg depending on how I drove. With these plugs I got a consistent 52 no matter how I rode. They also improved the start overall. I really like her. They performed well from 55 mph to 110 mph. The engine never missed a beat. I think you will like them.
