S&S 55MM PERFORMANCE MANIFOLD FOR M8

S&S 55MM PERFORMANCE MANIFOLD FOR M8

Engines are all about the flow, more air in and more air out, anything that slows that down, robs horsepower. The factory M8 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 and a must have for top level performance in the M8 platform. The factory plastic manifold is prone to warping and cracking causing intake leaks. This is a great choice for OEM replacement for reliability and performance!
