will wal mart carry this M1-209 filter ? and we are sure this will work on a 3.4 tacoma? i always get a little antsy when i am putting something this critical on my yota that is designed for another vehicle. am i correct in saying the use of a M1-209 is strictly for a little more capaity ? just so i can cross reference this for my own satisfaction what year and type of vehicle was the M1-209 designed for. thanks.
