Product Description

The 12" 4 Plugs Relocation LSX Ignition Coil Harness is meticulously engineered to provide exceptional ignition performance and advanced wiring management for complex automotive applications. Fully compatible with a comprehensive array of powerplants—including the LS, LS1, LS2, LS3, LS6, LQ4, LM7, 4.8L, 5.3L, 5.7L, and 6.0L engines—this high-performance automotive wiring harness serves as a critical infrastructure component for serious engine builds. It perfectly accommodates popular mainstream ignition coil models such as the D585, D514A, and D581. For facilities specializing in LS Swap engine transplants, this assembly offers a strategic architectural advantage by allowing coils to be relocated away from the intense radiant heat of the exhaust manifolds. This relocation capability is essential for clearing custom turbocharger piping and achieving a clean, wire-tucked engine bay aesthetic with hidden coils, ultimately optimizing both thermal management and long-term maintenance access.

Designed with a true plug-and-play architecture, the harness utilizes factory-standard premium connectors that deliver a reassuring, solid mechanical click upon engagement. This non-destructive installation method eliminates the need for wire cutting, splicing, or repinning, drastically reducing labor hours and installation costs for repair facilities and custom builders. The tactile feel of the heavy-duty outer jacket conveys its industrial durability, while the precision-pinned terminals ensure a secure, vibration-proof connection every single time.

The technical specifications outlined above reflect a strict commitment to uncompromising electrical performance and material integrity. By utilizing pure copper for the cable materials, the harness guarantees maximum conductivity with minimal resistance, ensuring that the ignition coils receive full, uninterrupted voltage for a powerful and consistent spark under heavy engine loads. The availability of premium connector types allows for precise integration into existing automotive, electrical, and industrial architectures. Furthermore, strict adherence to ITAF16949 and ISO9001 international quality management certifications means that every single unit undergoes rigorous 100 Testing before leaving the facility. This meticulous quality control provides procurement teams with the absolute certainty that large-scale deployments will yield stable, uniform performance across all installations, eliminating the risk of premature electrical failures.

Packaging and delivery

  • Packaging Details: PE bag/Carton
  • Selling Units: Single item
  • Single package size: 20X15X10 cm
  • Single net weight: 0.100 kg

Efficient logistics and secure transit are prioritized through our standardized packaging protocols. Each individual harness is carefully coiled and sealed within a durable PE bag before being placed into a protective carton, safeguarding the sensitive copper terminals and smooth rubber insulation from ambient moisture, dust, and potential abrasion during international transit. The compact single package size of 20X15X10 cm is deliberately calculated to maximize volumetric efficiency on standard shipping pallets, allowing distributors to optimize their warehousing space and reduce overall freight expenditures. At a single net weight of just 0.100 kg, the product remains exceptionally lightweight without sacrificing the dense, protective layering required for automotive-grade wiring, ensuring that bulk shipments remain highly cost-effective while arriving in pristine, ready-to-install condition.
