Spectre Universal Tube Elbow 4in. OD / 45 Degree (7in. Leg) - Aluminum

Spectre 97490 Universal 4in. OD Aluminum Tube Elbow - 45 Degree / 7in. Leg

The Spectre 97490 is a polished aluminum 45-degree tube elbow with a 4-inch OD and a 7-inch leg length, designed for use in custom cold air intake fabrication, intercooler piping, and performance air routing projects. Built from mandrel-bent aluminum for a smooth internal bore with no flow-restricting kinks, the 97490 provides a precise 45-degree bend to route intake air around engine bay obstacles without sacrificing airflow velocity. The polished exterior gives a clean, professional appearance under the hood. Universal fit makes the Spectre 97490 compatible with any 4-inch intake system.

Frequently Asked Questions

What is the tube OD of the Spectre 97490?
The 97490 has a 4-inch OD and is designed to pair with 4-inch ID couplers and matching diameter intake tubes.

Is the 97490 mandrel bent?
Yes. Mandrel bending maintains a consistent internal diameter through the bend, eliminating the flow restriction and turbulence that occurs with crush-bent tubing.

What is the difference between the SPE97490 and the SPE9749?
Both are 4-inch 45-degree aluminum elbows, but the 97490 has a 7-inch leg versus a shorter leg on the 9749, giving more room for coupler placement and routing flexibility.

Can the Spectre 97490 be used for intercooler piping?
Yes. The polished aluminum construction and smooth mandrel bend make it suitable for both intake and intercooler charge-pipe fabrication.

What couplers fit the 97490?
Any 4-inch ID silicone or PVC coupler will fit the 4-inch OD tubing. Spectre and other manufacturers offer matching couplers in various lengths and angles.

Is this tube compatible with a MAF sensor bung?
The straight leg sections of the 97490 can be drilled and welded for a MAF sensor bung if your application requires in-pipe MAF mounting.

Does the 97490 include couplers or clamps?
No. The 97490 is the tube elbow only. Couplers, clamps, and other hardware are sold separately.

Is this a universal fit or vehicle-specific?
The Spectre 97490 is a universal component for custom intake fabrication and fits any application using 4-inch diameter intake tubing.

Installation Notes

1. Dry-fit all intake components to plan the routing before final assembly.
2. Slide 4-inch ID couplers onto each end of the 97490 tube elbow.
3. Connect to the adjacent intake tube sections and orient to the desired routing angle.
4. Install hose clamps over each coupler and position over the tube ends.
5. Tighten all clamps securely to prevent air leaks.
6. Start the vehicle and confirm there are no boost or vacuum leaks before driving.
