Prestolite Spark Plug Wire Set

Prestolite ProConnect Spark Plug Wire Sets: OE Precision, Professional Results

When it comes to spark plug wire sets, few names carry the engineering credibility of Prestolite. As one of the largest original equipment ignition wire manufacturers for North American cars and trucks, Prestolite brings that same factory-level expertise directly to the aftermarket through its flagship ProConnect line of professional-grade ignition wire sets.

The ProConnect Difference: Built Where OE Is Built

Prestolite Wire is one of the largest manufacturers of original equipment ignition wire sets for North American produced cars and trucks, and ProConnect ignition wire sets are made in the same quality-certified manufacturing facilities as the original equipment. That means when you install a ProConnect set, you're getting the same manufacturing standards your vehicle saw at the factory — not a reverse-engineered approximation.

ProConnect ignition wire sets meet or exceed OE/OES specifications, performance, and quality, matching the original color and designed to provide exact cable lengths for a perfect fit in today's tightly packed engine compartments.

Triple Silicone Construction & Patented Prestosil™ Technology

What truly sets Prestolite's ProConnect wire sets apart from the competition is their proprietary layered construction. The wire construction starts with a carbon-impregnated fiberglass core, then a fiberglass braid for added strength, then conductive silicone for high-temperature performance. Prestosil™ insulation provides superior dielectric and heat performance with a reinforcing member for added strength, finished with a Class E silicone jacket to withstand heat, cold, chemicals, and moisture — and wire winding for critical EMI/RFI noise suppression.

ProConnect ignition wire sets are SAE J2031 Class E rated using three high-performance silicone layers: a high-temperature silicone jacket that withstands heat, cold, chemicals, and moisture; Prestolite's patented Prestosil™ silicone insulation for superior dielectric performance and heat resistance that exceeds OE/OES specifications; and a conductive silicone layer for high-temperature performance and EMI/RFI noise suppression.

Fit, Function, and Long-Term Reliability

The Prestolite carbon core wire set is resistant to fuels, oils, and other under-hood chemicals and utilizes stainless steel or zinc-plated steel for optimum strength, electrical conductivity, and corrosion resistance. Each set is engineered to match OE-specified insulators, nipples, terminals, and conductors. These cables fit tightly into spark plug wells to make installation quick and easy, resulting in a perfect connection and faster installations.

All ProConnect products undergo strict quality control and testing procedures, and come with a limited lifetime warranty. With 39 SKUs in the catalog covering a wide range of domestic applications — including marine-specific configurations with 135-degree spark plug boots for engines used in MerCruiser, OMC, Volvo, and other inboard setups — there's a Prestolite ProConnect set engineered for virtually any ignition system you're servicing.

Who Should Choose Prestolite ProConnect Wire Sets?

• DIY enthusiasts who want factory-correct fit without the dealership markup
• Professional technicians who need reliable, fast-installing sets that pass inspection
• Marine mechanics servicing inboard engines with Prestolite-type distributors
• Restorers preserving original color and length specs on classic vehicles
