Sierra's Premium Marine Wire Sets for inboard or outboard are durable and highly conductive. They feature Mag-core wire ignition and utilize a magnetic firing Kevlar core. The core is wound tightly with low resistance stainless steel wire that produces a high energy spark for superior performance, ensuring the wires have a long life.

These Premium Wire Sets prolong engine life as well by suppressing RFI/EMI and eliminating interference with on board electronics. Their corrosion resistant stainless steel spark plugs, distributor terminals and premium wire leads ensure maximum conductivity, while premium silicone jacketing and boots protect the wires from heat, dirt and moisture.
