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

• Each twin air filter is pre-oiled with twin air biodegradable foam filter oil, developed exclusively for twin air by chevron Texaco.
• Independently tested by the most prestigious engineering lab in Germany and was found to be the superior filter oil on the market.
• 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.
• 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.
• The filter is then placed in a temperature-controlled room to allow the oil to fully cure on the filter.
• The complete process provides maximum protection and maximum air flow you just open the resealable bag and install!
