Spectre 9749 Universal 4in. OD Aluminum Tube Elbow - 45 Degree
The Spectre 9749 is a polished aluminum 45-degree tube elbow with a 4-inch outside diameter, built for custom cold air intake fabrication and performance air routing projects. The mandrel-bent construction preserves a smooth, consistent internal bore through the bend, eliminating the turbulence and flow restriction that comes with crush bending. The 9749 pairs seamlessly with Spectre's complete line of 4-inch intake tubes, couplers, and air filters, or with compatible components from other manufacturers. A clean polished finish and universal design make the 9749 a go-to building block for custom intake systems.

Frequently Asked Questions
What is the OD of the Spectre 9749?
The 9749 is a 4-inch OD tube, compatible with 4-inch ID couplers and standard intake tubing.
How does the 9749 differ from the 97490?
Both are 4-inch 45-degree aluminum elbows. The 97490 features a 7-inch leg while the 9749 has a shorter leg, making the 9749 more compact and the 97490 better for applications needing extra straight length for coupler placement.
Is the Spectre 9749 mandrel bent?
Yes. Mandrel bending maintains wall thickness and consistent internal diameter through the bend for smooth, turbulence-free airflow.
Can the 9749 be used for intercooler charge piping?
Yes. The polished aluminum construction is suitable for both intake and intercooler charge-pipe fabrication.
What couplers fit the 9749?
Any 4-inch ID silicone or PVC coupler fits the 4-inch OD tubing.
Does the 9749 include clamps or couplers?
No. The 9749 is the tube elbow only. Couplers and clamps are sold separately.
Is this a universal fit product?
Yes. The Spectre 9749 is a universal component for any custom intake or intake piping build using 4-inch tubing.
Can I weld a bung onto the 9749 for a MAF sensor?
Yes. The aluminum tube can be drilled and welded to accept a MAF sensor or vacuum bung as needed.
Installation Notes
- Dry-fit all intake components before final installation to confirm clearance and routing.
- Slide 4-inch ID couplers onto each end of the 9749.
- Connect to adjacent intake tube sections and orient to the desired angle.
- Install hose clamps over each coupler and position over the tube ends.
- Tighten all clamps to ensure an airtight fit.
- Start the engine and verify there are no vacuum or boost leaks.
