With a 3.5\" outside diameter (approximately 89 mm), 2 mm wall thickness and an 84.8–85 mm inside bore, the tube is sized to accept trimming, splicing or welding so it can be adapted to many vehicle setups or fabrications. The surface receives a high-class finish and the tubing maintains a smooth internal profile to encourage steady airflow through modified systems.\u003c\/p\u003e\n\n\u003ch3\u003eHow will this pipe fit into my intercooler or intake setup?\u003c\/h3\u003e\n\n\u003cp\u003eThe tube works as a straight connector section between components in an intercooler or intake run. Its nominal 3.5\" OD and consistent wall thickness make it compatible with clamps, silicone couplers and weld joins. Because it’s a straight length, you can cut it shorter or weld elbows and flanges for tailored plumbing.\u003c\/p\u003e\n\n\u003cul\u003e\n  \u003cli\u003eOutside diameter: 3.5\" (89 mm) for common intercooler couplers\u003c\/li\u003e\n  \u003cli\u003eLength: 11.8\" (300 mm) ready to trim or join\u003c\/li\u003e\n  \u003cli\u003eWall: 0.078\" (2 mm) balances strength and weight\u003c\/li\u003e\n  \u003cli\u003eInside bore: ~84.8–85 mm for uniform flow\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eWhat materials and finish does the tube use, and why does that matter?\u003c\/h3\u003e\n\n\u003cp\u003eThe pipe is fabricated from 6061 aluminum alloy, a widely used automotive-grade material favored for its strength-to-weight ratio and weldability.

While a single straight section won’t create gains by itself, using smooth, properly sized piping reduces flow disruptions over improperly matched plumbing.\u003c\/p\u003e\n\n\u003cul\u003e\n  \u003cli\u003eUniform bore reduces pressure drop across the segment\u003c\/li\u003e\n  \u003cli\u003eStraight geometry helps preserve laminar flow where routing allows\u003c\/li\u003e\n  \u003cli\u003ePrecision manufacturing reduces internal irregularities that cause turbulence\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eWhat installation and customization options should I expect?\u003c\/h3\u003e\n\n\u003cp\u003eAC PERFORMANCE designed the tube specifically for custom work: it can be cut to length, welded to fittings or spliced with couplers. Its dimensions make it compatible with common silicone couplers and hose clamps, and it can serve as a building block in DIY intercooler piping, intake feeds, or cooling runs.\u003c\/p\u003e\n\n\u003cul\u003e\n  \u003cli\u003eCut to length for tight engine bays or custom routing\u003c\/li\u003e\n  \u003cli\u003eWeld or splice to other aluminum sections or fittings\u003c\/li\u003e\n  \u003cli\u003eUse standard clamps and couplers designed for 3.5\" OD tubing\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003cp\u003eWho this is for: This straight 3.5\" aluminum tube is suited to mechanics, fabricators and car enthusiasts who are building or modifying turbo intercooler plumbing, custom intake systems, or general-purpose ducting where a rugged, weldable aluminum section is needed.
