Karlyn 732 Spark Plug Wire Set OE-Style Ignition Wires

The Karlyn STI 732 Spark Plug Wire Set is a premium OE-equivalent ignition wire set engineered for reliable spark delivery and long-term durability. Karlyn/STI is a leading USA assembler of spark plug wire sets and an original equipment supplier to Audi/VW and BMW of North America, bringing OE-grade construction to the aftermarket.

Key Features:

• Silicone-over-Silicone construction — Double-extruded 8.0mm cable uses two layers of high-grade silicone, resisting temperatures up to 600°F for superior voltage protection and heat resistance
• 19-strand tinned copper core — Provides exceptional conductivity and corrosion resistance for reliable spark transfer
• German-engineered spark plug connectors — Corrosion-resistant, oversized clip-lock terminals ensure a positive electrical connection on every installation and reinstallation
• Permanently mounted silicone tips — Unlike OE glued designs, the silicone tips are permanently bonded to the connector, preventing tips from becoming stuck in plug wells during removal
• RFI/EMI suppression — Stainless steel magnetic conductive windings suppress ignition noise to prevent interference with radios, GPS, cellular devices, and onboard electronics
• OEM-style boots and connectors — Designed to match factory routing and connection points for a direct-fit installation; includes OE-type looms, sensors, and harness clips where required
• Resistant to heat, vibration, and corrosion — Built to withstand the harsh underhood environment for a long service life

Karlyn warrants this wire set to be free from factory defects. The Karlyn/STI line draws on over 40 years of partnership with German ignition specialist Bremi Fahrzeug-Elektrik, ensuring OE-quality components throughout.
