Maxima Foam Filter Treatment is one of the best airfilter oils produced. FFT is the culmination of 3 years development program which resulted in a synthetic polymer formulation that flows 4-12% more air and retains up to 8% more contaminates than all other brands. Resists both water and gasoline “fogging” wash out. Will not migrate off the filter, or dry out. Special solvent will not adversely effect either the foam element or the cement utilized to bond them together. This is our choice for air filter oil, used on all our own bikes and our race team bikes.
