Pros and Cons for all types of filters.
Pods definitely get the most airflow through, as you loose the restriction
of the airbox, but should duct cool air in to get the best out of it.
(its of note, that by losing this restriction, you can sometimes lose low end torque)
Its not the trust filter so much as foam filters in general, the foam 'decays'
(for lack of a better word) and eventually starts to break up, this can cause
problems further down the line, but this is just a part of owning and maintaining.
Same with re-oilable filters such as the TRD(?) and K&N. if you don't clean them,
they clog up, if you don't oil them, they clog up faster, if you over oil them you
can damage your airflow meter. Its a balancing act.
Its just common sense, nothing lasts for ever, but how long it lasts is up to you :)
