The Monster Sucker kit features our Big Sucker "hidden vent" technology and a larger filter surface area for maximum performance. Concealed vents include O-rings in the cylinder heads and injector/carburetor mouth outlet to provide proper engine ventilation, eliminating the need for external tubes and additional parts. The filter includes an integrated inverted front to draw in air not only from the side but also from the front, thanks to which more air is directed to the engine with the effect of obtaining more power Each filter is constructed of waterproof synthetic material, which in most cases eliminates the need for a rain cover. The filters are reusable and do not require oil, just rinse them to be able to use them again. Also compatible with 88-90 models; The breather system is not applicable for these years.
