1.7L Airfilter Replacement, Looking for filter replacement Options

[kbsmith1973]

I'm trying to replace the air filter element in my 1973 914 1.7L. Fram CA-383 was the prior replacement.

I got one from my local parts store, but it didn't fit properly. Subsequently I ordered one from one of the big Porsche outfits online. It was the same as the one from the local store!

The 'recommended' replacement has a larger inside diameter, causing it to miss the sealing ring in the lower part of the housing. It will leak outside air directly into the engine.

Internet search has not turned up anything on this issue. Any ideas?

There are a number of threads on this. Turns out the correct air filter is no longer available, despite what the online stores say.

There are, however, filters you can make work. Here's a thread where I made an adapter to use a NAPA Gold 2011 filter. The adapters are pretty simple to make, or I can make one for you ($20 plus shipping).

The NAPA web site shows the filter is currently about $7.50 each.

If you bought your filter from AutoAtlanta, it's probably the NAPA 2011. At least, that's what they sent me when I ordered a "correct replacement filter" from them 2 years ago.
