I have used them on several street engines (from low 12 to high 14) with very good result. I have yet to see any results from taking them of (like worse ET). I allways went with the old rule of 2" from top of stack to top of filter. There is a lot of debate in Sweden about them, but who cares.....let's show some real figures that show any claimed disadvantage. My 2 cents. Happiness is a HotVW!!
Have you made some kind of "cage" to get them standing 2" from the top of the stack?
If so, can you tell us how?
I`m using a slim but tall and wide spring inside my socks and that keep the socks from getting sucked in. Bought the springs at kollevold if I remember correctly.

Don't worry too much... I have driven my looker with nothing close to an airfilter for about 7 years now... I still run 13,6-13,9 on the 402m and it takes me safely all the way home afterwards. I guess it is time to open the engine and look at the real wear after the '06 season..
SOB/RFH:
PX has two sizes of filter sockings. The big one does not fit regular size stacks but the smaller one do. Just put the socks on, but don't push them down all the way and you have about 2" of clearense. If the socks are folding you have a big flow problem and need to clean the filter. A clena filter with oil on them will not collapse. You also don't want to tie them down with straps as maintenace is to time consuming. After a whole lotof street miles we have yet to drop more then the only one so far. I have built 4 out of 10 cars engines on the top 10 list and they all use the PX filters. Fitting a 48 IDA inside the stock 50' engine compartment is tricky and the ram horns need to be trimmed unless you use the short manifolds......but with short manifolds you have to have very flexible fingers and tools. So one gain is one loss.....the compromise of having the cake and eating it!! Happiness is a Hot VW!!
