Official FilterMAG
Distributor
We are now the official Australian Distributor of FilterMAG
products. In order for FilterMAG to remove minute steel
particles from the oil system, its magnets must have enough
energy to hold incredibly fine particles against the
velocity of the oil flow.
FilterMAG's patented design employs a focused magnetic force
field, that amplifies its incredibly powerful Neodymium
magnets, to generate the immense force needed to forcibly
remove tiny particles below 20 micron from the oil flow; and
retain increasingly smaller particles - as small as 2
microns - against the pressure of oil flow velocity.

Above is a video of Shane's 383ci powered Holden
Premier fitted
with one of our solid roller camshafts. In his own
words it "sounds a heap tuffer than the old crane
cam that was in it."
