AC PERFORMANCE 1.5" 90° Aluminium Elbow Intercooler/Intake Tube — 1.5" OD, Mandrel-Bent

AC PERFORMANCE's 1.5" 90° aluminum elbow is a mandrel-bent intercooler/intake tube section built from 6061 alloy for smooth airflow and custom piping installations.

This 90° elbow offers a compact, high-strength solution when routing intake or intercooler plumbing around tight engine-bay obstacles. With a 1.5" (38mm) outside diameter, 4" (100mm) leg lengths and a 1.5mm wall, the tube is engineered for fabricators, tuners and do-it-yourself builders who need a reliable connecting section that can be cut, welded or clamped into place. The mandrel bend preserves an even bore to reduce turbulence and support consistent airflow through turbo and cooling systems.

How does the mandrel bend improve airflow compared to other elbows?

The mandrel-bent profile keeps the internal diameter consistent through the curve, minimizing constrictions that cause pressure loss and turbulence. That smoother path helps maintain steadier airflow velocity and reduces the chance of hot spots or eddies that would impede system efficiency.

• Continuous bore through the 90° radius for minimal turbulence
• Reduced internal wrinkling compared with crush-bent tubing
• Improves flow consistency in turbo, intercooler and intake runs

What materials and dimensions should I expect, and are they suitable for fabrication?

This elbow is fabricated from aircraft-grade 6061 aluminum with a 0.059" (1.5mm) wall thickness and a 1.5" (38mm) outside diameter. The legs measure 4" (100mm) each, providing enough length for trimming, splicing or welding into custom plumbing layouts.

• 6061 aluminum alloy for a good balance of strength and weldability
• 1.5" OD and 1.5mm wall for common aftermarket intake sizes
• 4" leg lengths designed for cutting and fitting to adapters or couplers

How will the surface finish and construction affect installation and durability?

The elbow receives a high-quality surface treatment that improves corrosion resistance and gives a consistent appearance, while leaving the material ready for welding or clamping. Its construction supports repeated handling during template fitting and final assembly without compromising the wall integrity for pressure applications typical in intercooler and intake systems.

• High-class surface finish resists oxidation and looks consistent in visible installations
• 6061 alloy accepts TIG/ MIG welding and brazing when properly prepared
• Robust wall thickness suitable for pressure and vacuum sections in intake plumbing

Can I use this elbow in turbo, intercooler, and general intake plumbing?

Yes — the elbow is intended for universal use in air intake, turbo and intercooler piping where a 1.5" diameter and 90° direction change is required. It's a versatile component for custom builds, patch repairs or when replacing damaged sections of piping.

• Fits turbocharger plumbing, charge-air lines and aftermarket intake assemblies
• Compatible with silicone couplers, clamps and welded joinery
• Useful for both performance builds and practical routing solutions in engine bays

Who is this for: This elbow is designed for car enthusiasts, performance shops and fabricators who need a compact, durable 90° section to route intercooler or intake piping. It's ideal for custom turbo installations, retrofit projects and anyone who prefers mandrel-bent aluminum for smoother airflow and straightforward fabrication. If you work on charge piping or bespoke intake systems and want a clean, weld-ready elbow with predictable dimensions, this part is a practical and economical choice.
