18-498 Ness, Stage 1 Big Sucker air cleaner kit. OEM cover

If you are running a 1999 to 2001 Touring model with Magneti Marelli fuel injection, this Arlen Ness Stage 1 Big Sucker is the intake upgrade you need. It features a plain finish one-piece aluminum backing plate with the signature Ness hidden breather system, which vents the heads through internal channels to keep the setup clean. This kit is proven to increase horsepower, torque, and even fuel mileage by improving airflow through a radius inlet. It comes with a black pre-oiled air cleaner element and is designed to work with your OEM air cleaner cover or a custom cover with a central mount bolt. It is a straightforward bolt-on kit that makes a noticeable difference in how your early EFI bagger performs.
