V8 Ignition Wires – "IndestructaWires" – Shielded, Fiberglass Braid (1200 °F)

This listing uses our high-temp jacket: woven fiberglass braid (~1200 °F continuous, ~2048 °F melt).

Finish note: The matte motorsport-style fiberglass braid can hold fine shop dust more than silicone. A quick brush/air blast keeps it tidy. Prefer wipe-clean? Choose our Silicone-Coated version.

Built to Order for Your Engine

We cut every lead to length, choose the correct boot angles and terminations, and tailor your set to your vehicle and ignition system. Just tell us your engine, vehicle, and any mods.

Toughness You Can Count On

• Fiberglass (or silicone-glass) jackets shrug off header heat
• High-temp boots and reinforced ends prevent failure
• Built for survival—not disposal

Why Shielding Matters

We use 95%+ tinned-copper braid grounded to chassis for proven EMI/RFI reduction (20–60 dB typical). That keeps EFI, radios, and comms clean—on-road or off-grid.

Materials & Construction

• Core: ~0.04 Ω/ft ultra-low resistance
• Dielectric Stack: >50 kV breakdown margin
• Shield: 95%+ tinned copper braid, grounded (<1 Ω)
• Jacket: Fiberglass braid (~1200 °F cont., ~2048 °F melt)
• Boots: High-temp silicone (~450 °F) or ceramic (~2000 °F)
• Terminals: Stainless steel, matched to your ignition
• Diameter: ~10.5 mm finished with strain reliefs
• QC: Continuity and shield-to-ground verified on every set

Best For

• Classic V8s with distributors (carb or EFI conversions)
• High-heat bays (headers, turbo proximity)
• Off-road rigs that demand ruggedness and clean comms
• Builds with EFI, radios, or datalogging needs

Options & Upgrades

• Ceramic boots for extreme heat
• Color / finish options
• This listing uses Fiberglass Braid (1200 °F). For silicone-glass, choose our “Shielded, Silicone-Coated” version.

Optional: Quick Measure to Reduce Downtime

Want first-fit perfection? Use your old wires to measure and label lengths. If something’s off, we’ll fix it.

How to measure (5 minutes):

• Label each wire by cylinder (and coil wire if needed)
• Measure center-to-center length along the route
• Note plug boot angle and distributor/coil boot style
• List any routing notes or tight spots
• Snap a photo and upload or email with your order

Compatibility Note

If you have legacy or odd terminals (early Ford rings, marine, etc.) please contact us first. We do not build for coil-on-plug (COP) or coil-near-plug setups like GM LS, Ford Coyote, or modern Hemis. For custom ignition setups, send photos and we’ll confirm compatibility.
