Thanks to the multiple layers of cotton filter media, each pleat on the XStream is able to grab more debris while still retaining great airflow. It does this by integrating a top cap that is a filter itself, full of pleated filter media that provides increased surface area. More surface area equals more filtered air coming in for your engine to use.
Even better is that with the removable top cap, changing filters is easy because you’ll be able to see the interior position of the filter and check to ensure that it’s properly seated . You also won’t have to mess with lining up filter mounting hardware, just put the top cover on and everything aligns itself.
Specs:
- Increased filtration area with several pleats and filter media in top cap
- Better dust holding capability compared to your stock filter
- Epoxy-coated aluminum mesh backfire screen helps capture larger particles
- Custom base seal provides a precise and secure fit
- Washable and reusable
- Comes pre-oiled and ready to use
- Fits in your stock air box, no modification necessary
- Increased filtration area provides more air-flow while the 4 layers of woven premium cotton media allow for increased filtration
- XStream technology integrated into a two piece High-Flow Air Filter
- Two piece design makes installation, changing and cleaning a breeze
