HS42/061-45TC Alloy Manifold for Twin Cam Models (Rubber Flange not included)

This manifold is for use on all Twin Can engines with stock length cylinders and map sensor. When fitted with the purchased here separately, either HS42/062-42 Rubber Flange for 42mm carbs or the HS42/062-45 for 45mm carbs will position the HSR so as not to protrude out any further than stock with the benefit of better carburetor heat isolation, more secure mounting and a 2 to 3 HP gain over the standard item.
