Bosch 's O.E. fit Spark Plug Wire Sets precision engineered Opti-Layer Mag wire which delivers maximum firing energy for a longer more powerful spark and optimum ignition performance. High quality EPDM and Silicone coverings are used to resist high heat, oil and chemical damage for increased durability STI 's European wire sets are made with the finest copper core silicone wire which greatly exceeds O.E. and competitor specifications. The Asian wire sets come equipped with specially designed durable boots, corrosion resistant and oversized clip-lock terminals which allow for positive electrical connection every time you install or reinstall them. The result is smoother acceleration and improved fuel efficiency. You will notice smooth engine function during idling due to the Iridium Power Plugs low required voltage and high ignitability.
Acceleration is maximized because misfiring is reduced.
