From the site I noted above:I had no idea the cartidge was carboard compared to every other filter out there (that is metal). Pretty much the same thing as the Honda A02 filter, only with less pleats. Don't buy these crapy cardboard filters!!!
And, he had this to say about the Honda 15400-PLM-A02 filter:Also, the metal end-cap/"paper" end-cap question is another thing is used to cause alarm among users. Whether a filter has metal end caps or "paper" ones is of no consequence at all when the filter is used in its correct application. Whether metal or "paper" is used for the end caps, glue is still used to hold everything together, and the glue seams (and medium pleats) are the weakest points of any filter.
Honda is installing these filters on cars that are under warranty. That should say something right there.
