Went to replace my filter the other day, and found that the openings at the end of this filter were about 1/2-3/4" smaller than the filter already on there (which was another brand--either Porsche or Hengst).

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.

POST 1 / ORIGINAL POSTEROriginal post

Went to replace my filter the other day, and found that the openings at the end of this filter were about 1/2-3/4" smaller than the filter already on there (which was another brand--either Porsche or Hengst). The ends are ringed with a material that looks much like felt, and I'm wondering if this is supposed to be stretched as a part of normal installation. Anyone else run into this with this (or any other) filter?

POST 2Original post

The Porsche Branded Filter is the OX128/D

POST 3Original post

Put a little motor oil on both ends of the filter to soak the paper membrane around the center hole. Then push it on the male tube part in the filter housing with a slight twisting motion. Then do the same with the cover. Don't forget the new O ring. If you catch the threads, you're good to go. Use the mfgs torque spec.

POST 4 / ORIGINAL POSTEROriginal post

Turns out that while indeed the cutout in the felt-like material at the ends is smaller than the tube on which they are mounted, it is none-the-less the right part. The "felt" is a bit stretchy. Thanks for the feedback.

POST 5Original post

I think the nub the filter membrane goes over pokes a bigger hole in the membrane. When it folds over it helps create a seal. I found a little oil on the membrane helps ease the broaching process.

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