S&S Air Intake

S&S air intakes are the Harley-Davidson upgrade you fit when you want the airflow numbers to read different on the dyno, not just the cover to look different in the carpark. The Wisconsin company's Stealth air cleaner line is the clearest example — a sealed, low-profile assembly engineered around CFM measurement first and aesthetics second, with backing plates that bolt to factory intake studs and elements designed to flow without going through the usual catalogue compromises. Beyond Stealth, S&S supplies high-flow air cleaner kits for the carburetted Shovelhead and Evolution Big Twin generations, EFI-compatible kits for Twin Cam Sportster XL and Touring builds, and complete intake systems matched to the Milwaukee-Eight's electronic throttle bodies. The kits arrive with the gaskets, breather provisions, and torque values required to fit them right. Iron City Motorcycles, an authorised Harley-Davidson dealer in Leeds, stocks the S&S intake range for tuners chasing measurable midrange gains on Big Twin and Sportster platforms.
