Spectre GM LS3/LS7 Mass Air Flow Sensor Mount (Blade Style)

The Spectre GM LS3/LS7 Mass Air Flow Sensor Mount Blade Style (part number 9924011) is a precision-machined adapter that positions a blade-style MAF sensor correctly in the intake tract of LS3 and LS7 engine builds. Designed for custom LS swap intakes, aftermarket intake manifolds, and standalone EFI builds using a blade-style GM MAF sensor, the 9924011 mount provides a properly oriented, secure mounting point to maintain accurate airflow readings and prevent sensor errors. It is a straightforward bolt-in accessory that eliminates the need to fabricate a custom MAF bung or modify existing intake tubes.

Features and Benefits

• Purpose-built for blade-style GM MAF sensors used in LS3 and LS7 applications

Frequently Asked Questions

What MAF sensor does the 9924011 fit?
The Spectre 9924011 is designed for the blade-style GM MAF sensor used in LS3 and LS7 engines. This sensor style differs from the hot-wire style used in earlier GM applications. Verify that your specific sensor matches the blade style before ordering.

Is the 9924011 compatible with LS swaps into non-GM vehicles?
Yes. The 9924011 is specifically useful for LS swaps where there is no factory MAF mounting location on the intake tube or air box. It allows proper installation of the OEM or aftermarket LS3/LS7 blade-style MAF sensor in a custom intake setup.

Do I need this mount if I am using a factory LS3 or LS7 intake manifold?
If you are using the factory LS3 or LS7 air intake components, the MAF mount is already integrated. The 9924011 is intended for custom or aftermarket intake assemblies that do not include a factory MAF sensor provision.

Will this work with third-party standalone ECUs like MegaSquirt or Holley Terminator?
Yes, provided the ECU supports a GM blade-style MAF sensor input. The 9924011 positions the sensor correctly in the intake stream, which is what matters for accurate airflow data regardless of the ECU brand.

What is the difference between a blade-style and hot-wire MAF sensor?
A blade-style MAF sensor uses a sensing element mounted on a flat carrier that spans the air tube. A hot-wire MAF uses a thin wire element in a sampler tube. The LS3 and LS7 use a blade-style sensor. The 9924011 is designed specifically for that blade-style housing.

Can the 9924011 be welded into a custom intake tube?
Specific installation method will depend on the mount design, which may include a weld bung or flange. Review the included hardware and Spectre installation notes before proceeding. Consult a fabricator for weld-in applications.

Does this mount include the MAF sensor itself?
No. The Spectre 9924011 is the mounting adapter only. The GM LS3/LS7 blade-style MAF sensor must be purchased separately.

Is the 9924011 appropriate for track or competition use?
The 9924011 provides proper MAF sensor orientation which is important for accurate fueling at all RPM ranges including high-RPM track use. For competition builds running MAP-based fueling without a MAF sensor, this mount would not be required.

Installation Instructions

1. Identify the correct location in the intake tract for the MAF sensor, typically 6-10 inches upstream of the throttle body in a straight section of tubing.
2. Mark the intake tube for the mounting position, ensuring the sensor will be centered in the airflow with no obstructions immediately upstream or downstream.
3. Install the Spectre 9924011 mount per the included hardware and instructions, using the appropriate fasteners or weld process.
4. Insert the blade-style GM MAF sensor into the mount and secure per the sensor manufacturer torque specification.
5. Route and connect the MAF sensor wiring harness to the ECU or factory wiring, avoiding routing near heat sources or moving components.
6. Verify the sensor connector is fully seated and latched before starting the engine.
7. Start the engine and confirm no MAF sensor error codes are present. Perform an intake air leak check before returning to service.
