Description
xMeet the AC PERFORMANCE 4-inch outer diameter straight aluminum intercooler pipe, designed for versatile use across air intake and cooling system setups. Crafted from premium 6061 aluminum, this tube combines heat resistance with reliable strength to support a range of custom configurations. The brushed surface adds a refined look while keeping surface integrity, so the pipe stays visually consistent in both engine bays and workshop environments.
Versatile design for your build
This straight tube is specified with a 4-inch (102 mm) outside diameter and an 11.8-inch (300 mm) length. Wall thickness is 0.078 inches (2 mm), delivering a balanced blend of rigidity and weight. These dimensions make it suitable for straight-run intercooler piping, air intake paths, and related cooling lines where a clean, direct route is desired.
- High‑quality surface treatment provides a premium appearance and durable finish.
- Precisely machined geometry supports easy cuts, splicing, or welding for custom installs.
- Mandrel-bent aluminum tubing helps maintain uniform airflow, reducing sharp bends that hinder performance.
- Made from 6061 aluminum alloy, known for good heat tolerance and structural resilience.
Fabrication-friendly and installation-ready
The pipe is designed with adaptability in mind. Its straight profile and robust material allow it to be cut, spliced, or welded to fit a wide array of configurations. Whether you’re refining an existing intake setup or building a new intercooler route, this tube offers a dependable backbone for your project. The combination of a 4-inch diameter and a long, straight segment can help achieve a smooth, direct pathway for air and cooling fluids, while still accommodating common mounting and connector patterns in aftermarket builds.
Applications and compatibility
Use cases include air intake plenums, cooling system loops, and turbo intercooler piping where a straight, durable aluminum tube is advantageous. The 6061 alloy provides a solid foundation for higher heat environments and repeated handling during fabrication. This pipe is intended for universal use, making it a practical option for many makes and models where a 4-inch OD straight section is appropriate.
