Product Description

The Moroso 52037 is an Ultra 350 spiral-core spark plug wire set in red, built for 1999-2013 GM truck and SUV applications running LS/LQ engines in 4.8L, 5.3L, 6.0L, 6.2L, and 8.1L displacements. The Ultra 350 wire uses a stainless nickel alloy conductor on a spiral core at 350 ohms per foot, engineered to meet or exceed OEM specifications - a strong, cost-effective choice for street and performance applications.

The dual-layer high-heat EPDM jacket, separated by a nylon reinforcing pull tape, resists heat and flame while adding pull strength, and the inner insulation layer boosts dielectric strength with good RFI/EMI suppression. Silicone plug boots encase sure-grip, snap-lock terminals for positive connections, and the 8mm red wires use multi-angle boots for flexible routing in tight engine bays. The set comes complete for one engine.
