Allstar Performance Reducer AN Male -4 to -6 ALL49731

When you're running high-flow fuel or coolant systems, mismatched line sizes create unnecessary restrictions and pressure drops that rob your engine of performance. This Allstar Performance reducer steps down from -6 AN to -4 AN, giving you a clean, leak-free transition between larger and smaller diameter hoses without compromise. It's the kind of detail that separates a properly engineered fuel system from one that merely works.

Built from aluminum and black anodized for corrosion resistance, this fitting handles the demands of street and strip applications alike. The straight configuration ensures smooth flow and eliminates turbulence at the transition point—critical when you're dealing with fuel delivery or high-temperature coolant circuits.
