NAMZ 25' GXL Wire Spool - 16 Gauge - Blue NGWR-616

When you're building a custom harness or rewiring a race engine, you need wire that handles extreme temperatures and won't degrade under underhood conditions. NAMZ GXL wire delivers the reliability of automotive-grade insulation with the flexibility for tight routing in modern and vintage engine bays. At 25 feet per spool, you get enough length for most single-circuit applications without overbuying.

GXL insulation is thinner than standard automotive wire, making it ideal for custom harnesses where space is at a premium—a critical advantage in confined engine compartments and race car builds. The cross-linked polyethylene jacket resists heat, abrasion, and chemical exposure far better than standard PVC, ensuring your electrical system stays stable through extended high-performance driving.
