These spark plug wires are manufactured using the correct OEM materials. The FoMoCo logo is correctly placed on the spark plug boots which are made out of silicone rubber. Printing is lay lined exactly as original with correct font and spacing. Wires are cut to the precise length of the originals so they are tailored for the particular engine application. NOTE: Do not clean wires with Armor - All or other products that contain solvent. We recommend cleaning by using a very dilute soapy water solution on a damp cloth with very light pressure.
