Karlyn 773 Spark Plug Wire Set - OEM-Grade Ignition Wires

The Karlyn STI 773 Spark Plug Wire Set is a precision-engineered ignition wire set designed as a direct OEM-quality replacement for select Chrysler, Dodge, and Volkswagen vehicles. Assembled in the USA using German-engineered components, this set delivers reliable ignition performance and long service life.

Karlyn STI wire sets are built using an 8.0mm Silicone-over-Silicone dual-layer construction, providing superior voltage protection and heat resistance up to 600°F — far exceeding the single-layer silicone found on most competing wire sets. Every wire is pre-cut to the correct length for a hassle-free, no-trim installation.

Key Features:

• 8.0mm Silicone-over-Silicone construction — dual layers of high-grade silicone for maximum voltage protection and heat resistance
• German-engineered spark plug connectors — durable boots with corrosion-resistant, oversized clip-lock terminals for a positive electrical connection
• Permanently mounted silicone tips — no-glue design prevents tips from detaching and getting stuck deep in the plug well during removal
• Stainless steel magnetic conductive windings — deliver maximum spark energy while suppressing RFI/EMI interference with onboard electronics
• OEM-matched wire lengths — pre-cut to exact specification; no trimming required
• Made in the USA using OE-grade components in partnership with Bremi Fahrzeug-Elektrik of Germany

Karlyn STI wire sets are backed by a 12-month / 12,000-mile limited warranty against factory defects. Karlyn Industries is an original equipment supplier to Audi/VW and BMW of North America, reflecting the brand's commitment to quality and fitment accuracy.
