S&S Cycle

High Performance M-8 Manifold

"Big bore engines are all about the flow, more air in and more air out, anything that slows that down, robs horsepower," says S&S Cycle's David Zemla.

"The factory M-8 intake manifold does a decent job in stock form but starts getting in the way when trapped between 124" and larger cylinders. The stock polymer unit is also less tolerant of the additional heat that a big bore engine can make at full noise.
"The solution is the new S&S high flow cast aluminum manifold - a must have for top level performance in the M-8 platform. It adds 3-5 hp with a simple bolt on install and fits most M-8 models (Softail and Touring) from 2017 to 2021."
