Arlen Ness Big Sucker Stage 1 Air Cleaner for 1988-2022 Harley-Davidson Sportster
If you've looked at any gathering of Harley-Davidson motorcycles, it's highly likely you've seen a Big Sucker on the side of a few of them. There's a multitude of reasons for that.

Arlen Ness Big Sucker Stage 1 performance intakes for four-cam Evolution engines are a standby for experienced motorcycle mechanics, tuners, and riders because they work. The hidden breather system passes through the backing plate and exits inside the mouth of the throttle body to help eliminate the drips that come with OE breather systems and air cleaners.
The air cleaner can flow quite a bit of air, so if you're adding parts like cams with bigger lift or duration numbers, ported cylinder heads, or an exhaust with particularly good scavenging capabilities, the Big Sucker is a great choice. It won't suppress the gains made from other performance items like OEM pieces have been known to do in similar situations.
These kits have a variety of cover options depending on model and factory equipment; please see the notes to familiarize yourself with the available options for your motorcycle.
