Unreal intake manifold cost
Something to keep in mind as well: anything advertised online is "worth" more than something that isn't. It's all about the size of the market competing for the deal. When I say worth in this context, I mean the asking price will be higher.
You can find lots of good prices on parts with personal sales. You just gotta find the seller before they're looking to advertise to a larger buying pool. Find car clubs, race tracks, old guys fishing from the local docks, and even old mechanic shops and try make some friends. Bring some beers or other goodies their way when you show up, and it doesn't often take long to start getting leads.
