A must-have for every BSA B25 and B50 engine!

It is an gearbox saver with the magnet as part of the drain plug.

Easy to check each time you do an oil change to show any debris that could be in your oil from potential failings or wear on gearbox.

These are aluminium, but we also do a stainless steel magnetic drain plug for BSA unit singles.

Comes with a face mounted o ring as well.

Every engine deserves one of these!
