S&S Cycle Stealth Air Cleaner Kit — For S&S 58mm Throttle Body — 2014–2016 Twin Cam Touring

The S&S Stealth is the intake the aftermarket measures itself against. This Stealth kit is built for the S&S 58mm throttle body — the backplate to run when your Twin Cam already breathes through the big S&S throttle body. Underneath, the backplate's built-in stinger cone smooths air into the throttle body and the high-flow element breathes far better than the stock paper filter — a straight bolt-on upgrade for 2014–2016 Twin Cam Touring.

FITMENT

Fits Harley-Davidson Big Twin models with throttle by wire AND an S&S 58mm throttle body (S&S fitment statement: 2003–2017 Big Twin) — in our 2014+ Touring catalog: 2014–2016 Street Glide, Road Glide, Road King, Electra Glide, Ultra Limited, and Tri Glide running the S&S 58mm throttle body. This kit does NOT fit the stock throttle body.

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

Will this fit my throttle-by-wire Twin Cam?
Yes — this kit is built for 2008–2016 throttle-by-wire (electronic throttle) Touring models, which includes the 2014–2016 Touring bikes in our fitment list. It does not fit cable-throttle bikes.

Will this fit my stock throttle body?
No. This kit only fits the S&S 58mm throttle body. For a stock-bore throttle body, use the standard Stealth kits (for example S&S part #170-0301B).

Can you ship this to California?
No. This is a race-use-only part that does not conform to CARB standards, so we do not ship it to California — see the California Notice above. It is available to the other 49 states.
