Harley Davidson Original OEM Intake Manifold.4 Bolt Steel.Now here is a Very Rare Manifold.It is used of coarse so I took some good pics so you could see the overall condition,(see pics).I see some rust,dirt,grime pits,etc.I have to mention all I see.It measures.3.200" long.1.565" ID.1.565" Intake ID.1.705" OD.And .600" Thick.The bolt up plate is .235" Thick.I`m not sure on the exact Model for application,(just being honest).I will leave that up to the experts.The bolt up plate is not 100% flat,(it`s close),but you will need to run a gasket to take care of this,(I know you would anyways).I just wanted to mention it.As always,Please look at all pics so you know condition,(see all pics).Good luck bidding.Thanks for looking.
