Cotton is used instead of paper. Its qualities are:
- More air trapped: 40% increase allowing for better combustion
- Less engine wear - Almost unlimited lifespan
- Non-mechanical effect so not sensitive to moisture. Replacement filters reduce the pressure drop phenomenon. Lower pressure drop means more engine flexibility, which makes for a more comfortable drive.
This filter means a better mixture of combustion gases thanks to the extra air intake.
