True 102mm Legs for Maximum Grip : Unlike typical 90° elbows measured from the bend center, SIERRA's extended leg design offers full 102mm straight length on both sides for enhanced clamping and coverage.
Engineered for Turbo & Intake Systems : Designed for high-boost turbochargers, intercoolers, radiators, and custom air intake systems that demand longer, more secure pipe engagement.
4-Ply Reinforced Silicone Construction : 5.5mm thick wall with premium silicone and polyester layering—resists high pressure, vibration, and extreme temperatures -76°F ~ 482°F(-60°C ~ 250°C).
Smooth Bend Radius for Flow Stability : Precision-molded arc ensures optimized airflow or coolant circulation with minimal turbulence under load.
Build with Confidence : SIERRA components are trusted by tuners and builders for their reliability, consistency, and fitment accuracy in serious performance applications.
