VLR Retro Kits convert standard air cleaners into Enginaire VLR systems. The VLR offers lower restriction than an air cleaner without a precleaner and adds a centrifugal precleaner to the end of the air cleaner – extending filter life 50% longer than filter with a precleaner. Simply the best. Sizes fit many standard filters and the VLR mounts where other precleaners won’t.
