After cleaning the MAF on the Boxster I discovered that it is the same MAF used on Land Rover Bosch 4.0L and 4.6L V8s.

I just cleaned my MAF yesterday on my 01 Boxster, and can't believe how easy it was to pull out.

These are separate views of the same evidence. Frequency alone does not establish a fix, and these counts must not be added together.

Coverage and how to read this overview

Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

7 eligible posts · 0 unverified posts · 1 discussions match the subject in their title or opening post.

POST 1 / ORIGINAL POSTEROriginal post

After cleaning the MAF on the Boxster I discovered that it is the same MAF used on Land Rover Bosch 4.0L and 4.6L V8s. Surprisingly, we beat the crap out of them in the Rovers and they seldom have problems like they do in the Porsche engines. The software parameters must be much narrower in the 986 than in the V8 ECUs.

POST 2Original post

I just cleaned my MAF yesterday on my 01 Boxster, and can't believe how easy it was to pull out. I can't believe dealers charge upwards of $900 to replace them, when it literally is just a matter of opening your engine cover and undoing 2 tamper proof torx screws.

POST 3 / ORIGINAL POSTEROriginal post

With all the dead/dying Discovery 2 and Range Rovers out there, I am sure you could pick one up from the junk yard for twenty bucks.

POST 4Original post

Let me know If you guys need MAF for the boxster, I have them in stock, $150 Make sure to check your o2 sensors as well Thanks Leo [phone removed] [email removed]

..............LA Porsche Dismantler?...........

POST 7Original post

Does seem that way. I don't see any new parts listed on their site. Are advertising posts now allowed from parts suppliers? Given the notoriously poor reliability of MAFs in our cars it would seem to be false economy to take a chance on used. That's my feeling on most anything electrical that's critical to safe, reliable operation.

This is a source reference. Confirm exact model applicability in the original material.
