How to Install

S&S Cycle Chrome Tuned Induction System

Fitment Note: Model specific mounting brackets required and sold separately. 2.19"

• The heart of the single bore tuned induction system is the dual runner, two-into-one intake

• The tuned runners are very similar in appearance to the original dual runner intake for the now obsolete dual bore induction system, but the design allows for more flexibility

• Instead of bolting directly to a throttle body the runners of the single bore induction join together in a smooth, flow enhancing curve and the unit bolts to an adaptor bracket

• Like the VFI dual tuned runner system, the single bore tuned runner delivers a healthy boost in midrange torque. just what a street rider needs

• Peak horsepower is also increased

• The tuned runner system makes even more horsepower than an S&S teardrop air cleaner

• Performance increases are across the board for stock and big inch engines alike

• Requires one of the following adaptor brackets for your specific bike, sold separately

420-379 adaptor for 1984-2007 Big Twin with CV carb or Delphi EFI, chrome

420-380 adaptor for 1984-2007 Big Twin with Super ‘E’ or ‘G’ carb, chrome

420-381 for 1984-2006 XL with Super ‘E’ or ‘G’ carb, chrome

Sweet !


Perfect, order its bracket for fitment.


Quality parts, price & service at J&P Cycles just can't be surpassed. I'm extremely impressed, as usual.


Worked as described. However, on my 95" motor, it would stumble just a little bit when giving it throttle. May be better for a bit bigger engine or one with more modifications.


Couldn't be more satisfied.
