42in #4 Line -4 Str/-4 90 Deg 5pk

The ALLSTAR PERFORMANCE 42-inch #4 Line -4 Str/-4 90 Deg 5-pack is a professional-grade hose assembly set designed for high-performance automotive cooling, fuel delivery, and hydraulic systems in street rods, race cars, and custom vehicles. This product is essential for mechanics building or maintaining modified engines, connecting radiators, fuel systems, and power steering circuits with precision engineering and durability.

Each 42-inch hose features -4 AN fittings, including one straight and one 90-degree adapter molded directly into the line, which eliminates the need for separate fittings and reduces potential leak points in your plumbing. The #4 line size is designed to handle moderate flow rates typical of secondary cooling circuits, remote oil coolers, and fuel systems on naturally aspirated and lightly boosted engines.

This 5-pack format ensures you have multiple hose runs ready for complex fuel line routing, intercooler piping, coolant loops, or remote reservoir installations common in turbocharged and supercharged builds. ALLSTAR PERFORMANCE's automotive-grade construction uses reinforced synthetic rubber and braided covering rated for sustained pressure cycles, vibration resistance, and chemical compatibility with modern coolants, synthetic oils, and fuel additives—essential for long-term reliability.
