Paper or plastic?
Personally if I only had to choose between a regular paper air filter and a foam one I'd choose the paper every time.
Fortunately there are OICG (oil-impregnated cotton gauze) air filters that most high-performance applications and even helicopters use, that is my first choice, mainly for the better airflow characteristics.
There are some rumors about higher silicon levels when oil lab tests are made and the rumors blame this on sand passing through the filters, a filter manufacturer says it's from the oil used on the filters having silicon in it, but I have not seen any data to support either claim and it appears to me the silicon level thing is just a scam to sway buyers to other filters. Having run the OICG type filters since 1978 I would know if any sand passed through the filters, and with over 150,000 to 200,000+ miles on many vehicles in that time and various engines disassembled for inspection or modifications and no indications of grit or sand passing through the filters or engines.
Now here is a real WARNING...
If you are considering a foam air filter, here are a few things to think about...
It's not too difficult to imagine the horror you'd feel if a dirty foam filter deteriorated and emptied all the dirty contents, it held for who knows how long, in to your expensive turbocharger and expensive high compression diesel engine. Even if lucky enough not to have it fail completely, just a tear can let a lot of dirt that built up on the filter and other unfiltered air pass. Air like water tends to follow the path of last resistance or least restriction, so the majority of air would enter the hole or tear and rapidly wear away the foam to make a bigger and bigger path, as shown in by the photo below.
So if someone is trying to sell you a performance air filter, make sure you ask what the media material is, and if it is foam, RUN!
I would seriously question the credibility and actual experience in the automotive business of anyone recommending one of those foam filters for your turbo diesel engine.
Fortunately foam filters are not too popular, and for good reason...
Paper or Plastic? Well foam should be out and paper is OK, but you may want to consider a Hi-Flow oil impregnated cotton gauze (OICG) type air filters, better flow for better breathing that should result in power and mpg gains.
