B0303 ENGINE MAINTENANCE OIL

MUGEN Air Filter Oil (100ML)

This is an excellent sticky oil to keep dirt and dust from entering your carburettor.

The best method is to pour a small amount of oil in a plastic bag and then put your
filter in the bag and squeeze the filter so the oil distributes throughout the foam.
The oil is very thin so make sure you squeeze any excess oil out before installing on your car.
Once the oil dries it will become very sticky.

NOTE: Wash out your filter after every 2 or 3 meetings. It will help protect your expensive engines!
