Im currently running M1-111 filter, and im thinking about switch for M1-302 it 2 time longer then M1-111. just wonder it can use engine damage or any benefic ? thanks
Not too many downsides to it as long as it's not going to be more vulnerable to road hazards and whatnot. If you're into extended drains, I'd say that you'll offset the effects of loading a bit.
some of the manufacturer's will save money on filter medium by not folding the pleats as tightly on the longer filters, but the better ones will have more surface area, which equals a better filter.
