General Installation Practices

NOTE: Disconnect Battery

Before unplugging your MAP sensor, it is important to disconnect both batteries and let the ECM discharge for at least 15min.

If you rush this step and unplug the MAP sensor, it can flag a Check Engine Light in the ECM on startup.


MAP Sensor Relocation Kit Installation

Locate MAP Sensor

1. Locate MAP sensor.

It is found on top of your intake manifold.

Slide locking Tab

2. Unplug MAP sensor.

Slide the locking tab back, then depress it to unlock the plug from the sensor.

10mm and remove bolt

3. Remove 10mm Bolt

Use a 10mm socket to remove the bolt; you’ll reuse it on the Banks MAP Spacer.

Twist and Remove

4. Remove MAP sensor

Twist and lift to free it from the intake manifold.


Use MAF cleaner only

Important: Use Mass Air Flow Cleaner Only.

Solvents such as brake cleaner will damage the sensor.

While GM does not recommend cleaning, we have seen favorable results using Mass Air Flow (MAF) Sensor Cleaner, available at most auto parts stores.

Remove deposits

5. Clean MAP sensor

Try not to overly spray the sensing wire; a rag or brush can be used for stuck-on debris.


6. Install MAP sensor into Banks Spacer

Twist while inserting the MAP sensor to prevent O-ring damage. Thread the 20mm long T-30 Torx screw by hand, then tighten snugly with the supplied Torx Key

Insert O-Ring

7. Install O-Ring

Don’t forget to install the newly supplied Viton o-ring into the Banks MAP Spacer.

Use Torx Bolt and Key

8. Install 20mm Torx Bolt

Tighten snugly by hand, a T30 Torx key is supplied.

Re Connect Harness

9. Reconnect MAP sensor

Be sure to slide the locking tab forward into place. Double-check that all bolts are snug, and enjoy your new Banks MAP Spacer.
