LEDAUT Spark Plug Heat Shield and 12pc Engine Wire Separator Kit — Red, 6" Fiberglass Sleeves for 8-Cyl (8/9/10mm) — Insulating, C

LEDAUT Red spark plug heat shields and aluminum wire separators protect spark plug boots and organize engine wires under extreme temperatures.

Keep your ignition components safe and tidy with this kit that pairs six-inch fiberglass heat sleeves with precision aluminum dividers. The insulating sleeves resist very high temperatures and let you route plug wires directly over hot headers or tight engine components without degradation. Meanwhile, the anodized aluminum separators secure and space wires for a cleaner engine bay and reduced electrical interference.

How much heat protection do these sleeves provide?

The sleeves are woven from high-temperature fiberglass designed to withstand hundreds of degrees, keeping spark plug boots and wire jackets from becoming brittle or damaged. Their double-layer construction improves insulation and durability compared with single-wall covers.

• 6-inch length covers most common boot-to-wire transitions
• Fiberglass fabric resists sustained high heat exposure
• Double-wall build adds thermal barrier and abrasion resistance

Will the separators fit my spark plug wire sizes and engine layout?

The included set of 12 aluminum separators accommodates popular spark plug wire diameters and organizes wires for 8-cylinder engines. The lightweight, corrosion-resistant material secures wires in parallel runs, preventing crossfires and improving routing clarity in tight engine bays.

• Compatible with 8mm, 9mm, and 10mm ignition wires
• 12-piece kit supports tidy routing for 8-cylinder setups
• Aviation-grade aluminum offers stiffness without excess weight

How does this kit affect ignition reliability and maintenance?

By insulating boots from radiant heat and keeping wires spaced apart, the kit helps reduce the potential for heat-related misfires and premature cable wear. Organized wires are easier to inspect and service, which simplifies troubleshooting and routine maintenance.

• Reduces heat transfer to boots and wire insulation
• Prevents rub-through and chafing against hot surfaces
• Makes visual inspection and replacement quicker and safer

How simple is installation and what vehicles are supported?

Installation is straightforward: slide the sleeving over the wire and position the separators along the harness where needed. The universal dimensions and flexible material fit most straight or angled boots across a wide range of race, street, and performance vehicles.

• Slip-on sleeving requires no special tools
• Separators mount easily to existing fasteners or bezels
• Suitable for many performance and street eight-cylinder engines

Who is this for: This LEDAUT kit is aimed at automotive enthusiasts, track-day competitors, and professional teams who need durable thermal protection and a neater ignition layout. If you work on race cars, project builds, or simply want to extend the life and reliability of your spark plug wires while improving engine-bay appearance, this set delivers practical heat resistance and organized routing.
