Frequently Asked Questions
What are the exact diameter and bend specifications for AEM tube 9-21070?
Match the listed outside diameter, bend angle, radius, leg length, wall thickness, and material to the planned intake layout before ordering.
Is this tubing a direct-fit vehicle part?
Unless a specific vehicle application is listed, intake tubing is a universal fabrication component that requires layout, measuring, and compatible connections.
Can the aluminum tube be cut or modified?
Universal tubing may be cut for a custom installation, but measure twice, deburr every edge, clean out all chips, and preserve enough straight length for couplers and clamps.
What couplers and clamps fit this tube?
Select couplers and clamps by the tube's measured outside diameter and the mating component. Allow for reducer sizes when the two ends differ.
Does this component include a MAF sensor provision?
Only use a sensor provision if it is explicitly shown and specified for this MPN. A universal bend or tube should not be assumed to include a calibrated MAF housing.
Will custom intake tubing require ECU tuning?
Changing MAF housing diameter, sensor placement, or airflow characteristics can require calibration. Consult a qualified tuner before changing metered-air geometry.
Installation Instructions
- Confirm AEM part number 9-21070, the complete application, and all included components before starting.
- Mock up the complete intake path and mark cut locations only after verifying sensor, coupler, hood, engine-movement, and heat clearance.
- Cut with the appropriate tool, deburr every edge, and remove all chips from inside the tube.
- Join components with correctly sized couplers and clamps, supporting the assembly so its weight is not carried by a sensor or throttle-body connection.
- Pressure-check or inspect every joint for leaks and verify safe clearance before starting and driving the vehicle.
