Original Sump Drain Plug, with magnetic pick up. The washer for this is AED172.
If this original sump plug has stripped the thread in the block try our self threading plug
DP2. Always thoroughly clean the magnetic part when doing an oil change and replace sump plug if the magnet seems weak as it needs to pick up all the metal debris/sludge working its way through your engine.
Tighten to correct torque of 25lbs only--IF you want a super magnet that will surprise you how much debris is in your gear case see
DP3.
