Review on Sierra International 18 8811 1 Premium MagForce by Jason Peterson

Initially I was very happy with the fit of this product. I used them for literally 3 rides before I had to transplant them (the lid and rotor are brand new too) when I went to transplant one of them fell apart like butter. The inner clip that connects to the top of the spark plug just fell out of the spark plug boot. I wouldn't recommend them to anyone as they fall apart once you complete a basic task like changing spark plugs. I will change my rating if the company refunds my money or replaces the damaged wire.
