Review on Proform 141 638 Linear Spark Plug by Josh Schweitzer

I wasn't impressed. I probably would have kept them, but the plastic was broken. yes plastic Didn't expect plastic. The main part is made of chrome steel. The black plastic pieces are held in place with small screws under metal caps that slide together to hold the wires in place. The one I received had a broken plastic part so it couldn't be assembled. I wasn't expecting plastic and thought it was aluminum instead of steel. The edges are rough. The bow tie logo is a thick rubber/plastic sticker. let's go back and back to search.
