J's Racing Magnetic Drain Bolts

Purchased second hand off Dotty from itr-dc5 and Type R Owners.

The magnetic drain bolt uses a 5,200 gauss magnet that catches iron powder and sludge floating in the engine oil. By catching those particles before they cause damage to the engine, the magnetic drain bolt contributes to extending the engine overhaul cycle. Enuff said really. Prevention is better (and cheaper in this case) than cure.
