The replacement of standard air mass sensors is often hampered through the use of special screws.
These TS25 and T20 AFM Extraction Bits are specialised OE tools suitable for this task.
The Pierburg AFM Extraction tool bits feature a solid post located at the centre of the star. Due to the bore on the face side of the insert bit these special screws can be unscrewed.
Standard 6.35mm (1/4”) bit to suit commercially available ratchets or socket wrenches.
