I going to get into dismantling the AC system to flush out the old oil & debris after a compressor failure, system clog. Several responses (both here and on the Porsche "rennlist") suggested installing a low side inline filter to catch any stuff I dont get out with the flushing.

Any thoughts on what filter and where to get it?
Is it a bolt in thing (inline with existing hook ups or will I have to bring the low side line to someone who makes hoses & high pressure lines and fit some threaded ends on?

You need to find an independent auto air conditioner supply and/or shop. They can supply this. It is a very good step to take after a compressor failure.

Good luck,
