Product Description

The Moroso 51046 is a universal Ultra 350 spiral-core spark plug wire set in black, built to work with both HEI-style and non-HEI-style distributor caps. 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 black wires use multi-angle boots for flexible routing. The universal design makes the set adaptable across a wide range of distributor setups.
