18-361 Ness, Stage 1 Big Sucker air cleaner. Beveled Black

This Arlen Ness Stage 1 Big Sucker air cleaner kit is a solid upgrade for riders looking to squeeze more horsepower and torque out of their Twin Cam. It features a sharp black anodized Beveled outer cover and a matching black backing plate. The high-performance cotton gauze filter comes pre-oiled with black oil, ready for the road. What I really like about this setup is the patented hidden breather technology; the backing plate is o-ringed at the heads and vents directly into the throttle body, so you don't have to mess with any external hoses or hardware. It fits 1999 to 2006 Twin Cam models with CV carbs, 2001 to 2015 Softails with Delphi fuel injection, 2004 to 2017 Dyna models excluding the 2017 FXDLS, and 2002 to 2007 Touring models.
