The BOOST Products MAF honeycomb airflow straightener helps calm turbulent airflow before the mass air flow sensor in a custom intake or turbo inlet pipe.
Fitment Information
- For custom air-intake, cold-air-intake, and turbo-inlet tubing with a mass air flow sensor
- 3.0 inch / 76mm tubing
- 3.5 inch / 89mm tubing
- 4.0 inch / 102mm tubing
Fitment Note
This is a build-specific intake insert, not a vehicle-specific part. It installs inside the intake tube directly ahead of the MAF sensor. The actual outer diameter of each honeycomb is approximately 4mm smaller than its listed tube size, allowing it to fit tubing with a 2mm wall thickness. Confirm your intake tube inside diameter before ordering.

Product Description
A MAF sensor needs a stable airflow signal to report accurately to the ECU. When a custom intake, larger turbo inlet, or revised pipe layout puts turbulent air in front of the sensor, the signal can become inconsistent. This aluminum honeycomb insert is designed to straighten that airflow before it reaches the MAF.
It is a simple addition for a custom intake tube where the MAF location is known to be sensitive to airflow changes. The 20mm-thick insert slides into the tube ahead of the sensor and is available in three common intake-tube sizes.
Before You Buy
This part can help address airflow stability at the MAF sensor, but it does not replace proper intake design, leak checks, data logging, or calibration work. Check the available space ahead of the sensor and make sure the selected insert matches the tube’s actual inside diameter. Do not install it where it could contact the MAF sensor element.
