S&S Cycle 70mm T143 Induction Kit for 2006-2017 Harley-Davidson Big Twins
A high-output T143 engine needs air delivery to match its capability, and the S&S induction kit delivers exactly that. The matched throttle body, injectors, and air cleaner work together as an integrated system rather than a collection of parts, giving the T143 the fuel and air it needs to breathe freely across the entire power band.
