Porting L98 MAF
Removed my MAF and looked inside.
The metal fins appear to be very close to the sensor with no seperation possible. Any suggestions on grinding them out safely?
I have my screens removed already.
Thanks
Roger

No problem.
Carefully cover the ends of the sensor tube with duct tape.
Cut the heat sink fins off as low as possible with a hack saw or other.
Dress the cuts with a Dremel.
Wipe & blow out any debris.
Remove the duct tape.
Install the MAF.

DO not hit the sensor element inside with that hacksaw, or you may permanently damage the sensor.
I would not even attempt to remove the heat sink fins, just do the screens.

I have done this twice, never felt a difference. Had one done professionally and did one my self with a sawsall. Have to be verrry careful. As vader said, pull the screens and call it good, unless you have a totally maxed out stroker or similar.
