fused outer and inner elements prevent dirt and grime from being lodged between layers. unlike twin air, this can be a problem with two-piece designs. trapped particles can restrict airflow and if dirt works its way into your engine, a pinhead sized granule will gouge your cylinder, piston and rings. thick, flat foam, greaseless sealing ring ensures maximum contact with your airbox while acting as a breathable gasket for increased air passage

1. coarse open-pore foam catches airborn dirt, grime and sand
2. Each twin air filter is pre-oiled with twin air biodegradable foam filter oil, developed exclusively for twin air by chevron Texaco.
3. Independently tested by the most prestigious engineering lab in Germany and was found to be the superior filter oil on the market.
4. fine open-pore inner foam acts as a second filter to trap the smallest particles while ensuring maximum air passage
5. exclusively formulated adhesive withstands repeated cleaning. even with harsh solvents or gasoline
6. The process begins with a brand-new twin air dual stage foam filter, using the same foam (polyester), glue and hand-crafted care that has defined the twin air standard.
7. Using our new state of the art filter oiling machine, each filter is completely submerged in twin air bio-oil and massaged to perfection to ensure that all pores are evenly coated.
8. twin air filters are slightly smaller than stock filters to increase air space around the filter and improve circulation
9. The filter is then placed in a temperature-controlled room to allow the oil to fully cure on the filter.
10. The complete process provides maximum protection and maximum air flow you just open the resealable bag and install!
