Rugged, lightweight, self-supporting, and completely disposable combination air cleaner and filter. • Function well under severe pulsation conditions, particularly two- and three-cylinder engines. • Vibration-resistant media is secured into molded housings of rugged ABS plastic—so they don’t fall apart as other designs might. • Easy to install, durable, and reliable. • Completely disposable — acceptable for normal trash pick-up (DuraLite should not be incinerated).
