Fast delivery but no instructions and wrong part included
by Tim from Winston Salem, North Carolina on May 20, 2016
I received my spark plug wiring kit, however there are no instructions and did not include the correct tip clips to put on the spark plugs , now I have to return them or spend more money and time and order new boots with correct tip clips included....Very frustrating! Save yourself time and order the spark plug wires already assembled for your model engine. What a PIA this turned out to be!
