Testing shows that by simply installing a Big Sucker kit, horsepower gains of up to 21% are attainable. The air filter elements are made one at a time using the finest materials available. The red hue filters are all pre-oiled, and feature four layers of surgical-grade cotton to promote airflow and filter air effectively. The filters are hand-poured one at a time in a urethane body, unlike many other filters that are spun, which can leave a residue on the filtration media. The Big Sucker air filter kit features a one-piece aluminum backing plate and eliminates the need for banjo fittings, hoses and a filter. The breather exits at the mouth of the throttle body, creating a virtually closed-loop system.
