1. Disconnect and remove your MAF sensor from your vehicle. Place it on a clean workbench. Use a torque screw socket to remove the 4 torque screws supporting the housing. (Pic. 1 )

2. Separate and remove the stock housings from the MAF sensor.

3. At this point take B.P.P’s housing and insert the O-ring provided into the grove on the housing. (Pic. 2 ) Assemble all three sections together with the white air foil/sandwich between them (only on upgraded model) . On standard model there will be no Airfoils. (Pic. 3 & 4)

4. Use your original screws to tighten your MAF sensor together.

5. Reinstall your MAF sensor into you vehicle.

It is always better to reset your computer after this install to enhance your performance
