Zreneyfex 10-Pack 9mm Spark Plug Wire Set for Ford 5.0L/5.8L SBF 302 — Blue Silicone, HEI Boots

Zreneyfex 10-pack 9mm spark plug wire set is a direct-replacement ignition wire kit engineered for Ford small-block V8 engines from late-1970s through mid-1990s, offered in a durable blue silicone jacket.

These ignition leads are built to restore reliable spark delivery on Ford SBF 302 Windsor 5.0L and 5.8L applications where original wiring has aged, hardened, or cracked. The set includes ten color-matched wires with 9mm high-temperature silicone insulation, designed to fit HEI distributor and coil-in-cap systems found in Mustang and F-150 models from the specified years. This kit replaces the common worn-out wires while keeping routing and boot types compatible with OEM-style connectors.

What vehicles and engines will these wires fit?

This wire set is intended for Ford small-block V8 vehicles listed across the 1964–1995 Mustang range and 1979–1995 F-150 models, specifically matching 5.0L and 5.8L (SBF 302 Windsor) ignition layouts. Confirm your engine type and distributor/coil arrangement before purchasing.

• Compatible with Ford Mustang 1964–1973 and 1979–1995 model years where SBF engines were used
• Fits Ford F-150 pickup truck model years 1979–1995
• Designed for 5.0L (302) and 5.8L small-block V8 engine configurations

How are these wires constructed and why does that matter?

The wires use a 9mm diameter conductor encased in a pure silicone outer layer rated for high temperatures, which helps resist cracking, oil exposure, and heat degradation common in engine bays. Durable boots match HEI distributor angles and straight spark plug connectors for proper seating and long-term insulation integrity.

• 9mm core for consistent spark transfer and minimal interference
• Pure silicone outer insulation for heat and chemical resistance
• Black 90° HEI distributor boot and black straight spark plug boots for correct fit

What exactly is included in the package and what is not?

The kit ships as a ten-piece wire set in blue, sized and pre-terminated for direct replacement of each plug-to-coil/distributor lead on applicable engines. This product set does not include a separate coil wire; it only contains the spark plug/ignition leads for the standard firing positions.

• Includes: 10 high-temperature blue spark plug wires pre-terminated
• Boot types: 90° boot for HEI distributor end, straight boot for spark plug/coil-in-cap
• Excludes: dedicated coil wire or additional ignition components

How should I install and maintain these wires for best results?

Installation follows standard spark plug wire replacement steps: route wires following factory paths, avoid sharp edges and hot manifolds, and ensure boots fully seat on spark plugs and distributor/coil posts. Periodic inspection for cuts, soft spots, or loose connections will extend service life.

• Route wires away from exhaust and moving parts to prevent heat and abrasion
• Match wire lengths to firing order and clip into existing retainers
• Check connection security at boots after initial heat cycles and at routine service

Who is this for: This Zreneyfex wire set is aimed at classic Ford owners, hobbyists restoring or maintaining Mustang and F-150 models with 5.0L or 5.8L small-block engines, and DIY mechanics who want an OEM-style replacement with improved silicone insulation. Choose this kit if you need a full ten-wire replacement with HEI-compatible boots and clear fitment for late-20th-century Ford V8 applications.
