High hopes for filter wrap
I've bought three S&B pre-oiled filters for my '16 Ram 2500 and each time they've performed well, up until getting clogged with bugs and debris. Hopefully this wrap will prevent the heavey stuff from getting into the filter and clogging the pleats.

S&B all the way
I run S&B filters on everything I can. 2 Ram trucks, sxs and one eventually on my Gladiator!
