The filter material is a tightly woven cotton fabric, which compared to the cotton gauze used in other filters, performs better without sacrificing filtration, and will not fray. The deep pleats add up to 20% more filtration surface compared to the OE paper filter.
A precision molding process minimizes rubber seepage into the filter material, ensuring maximum performance.

Oiled vs Dry Filters
We chose an oiled filter design because it offers a significant performance advantage with the only drawback being it takes a few more minutes to clean. Servicing a dry filter is a little easier but the performance is not much better than the stock paper filter.
How is this possible? The synthetic, sensor safe, oil captures dirt particles while adding very little flow restriction to the filter material. Without oil a more restrictive filter material is needed to maintain the same filtration ability.
