S&S Cycle Stealth Air Cleaner Kit — Teardrop, Lava Chrome — Gen 2 M8 (2023–2026)

S&S rebuilt the Stealth for the center-cooled Gen 2 Milwaukee-Eight: a larger throttle-body opening and the high-flow Stealth element behind it, for a measured 38% increase in airflow on S&S's bench. Includes the teardrop cover in Lava Chrome — the classic S&S teardrop in the dark smoked-chrome finish.

INSTALLATION

Air cleaner installation is a bolt-on job with basic hand tools: the stock air cleaner comes off and the S&S backplate, filter, and cover bolt on in its place. Follow the S&S instruction sheet included in the box for torque specs and breather routing. S&S publishes an official Stealth install video — it is embedded below.

QUESTIONS RIDERS ASK

What counts as a Gen 2 M8?
The center-cooled second-generation Milwaukee-Eight: 2023.5-up CVO Street Glide/Road Glide and the 2024-up Street Glide and Road Glide. If your M8 is a 2017–2023 model, you need the first-generation M8 Stealth kits instead.

Can you ship this to California?
Yes. S&S publishes CARB Executive Order D-355-50 for this part, so it is legal for sale and use in California on the models the EO covers — see the California note on this page.
