It quickly turned out that using a fairly simple method could effectively counteract this phenomenon. This is how the TWIN AIR double-layer sponge filters were born, whose design combines high efficiency with full engine protection. | Additionally, over the years, TWIN AIR designers noticed other problems related to the length and width of seams (gluing), which reduced the air flow, adversely affecting the operation of the engines. This was also changed thanks to the use of innovative micro-gluing technology.| To sum up, TWIN AIR filters are characterized by: | - laminated, fire-resistant double-layer foam,| - durability estimated at approx. 40-50 washes and soaks, | - high quality and precision of workmanship, which is manually controlled. | Country of origin: Netherlands.|
