The Big Sucker is designed to give your engine maximum airflow for maximum performance. The Stage 2 kit differs from the Stage 1 by including a 20% larger air filter element. Testing shows that by simply installing a Big Sucker kit, horsepower gains of up to 21% are attainable. Big Sucker kits feature patented, hidden breather backing plate technology - this means the breathers are incorporated into the air cleaner housing itself. Each hidden breather has a sealing O-ring at the heads and exits at the carburetor or throttle body inlet to provide efficient internal engine pressure relief.
Standard 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. The Stainless Jacketed Filter differs from the Standard Filter in two areas: The mesh supporting the gauze is made of a rust-resistant stainless steel as opposed to standard carbon steel, and the synthetic filtration gauze is in black or dark grey, rather than the pink/red hue of the Standard Filter. Includes Big Sucker backing plate, high-flow filter, chrome banjo bolts, gasket, hardware, and simple instructions.
Note: Air cleaner images are for reference only. All filters kits will come with your choice of filter.
