I have a used RPM Air-Gap intake manifold for Magnum engines, going with EQ LA-pattern heads on my 5.9L Magnum build so I don't need it anymore. I thoroughly cleaned it and took out all the fittings except the water bypass. It's bare aluminum which I cleaned with acid-based Mag Wheel Cleaner so it'll stain if it's touched with bare hands, I can paint or clear-coat it if wanted. Looking for $280 plus shipping or trade for a non-Air-Gap Performer RPM intake for LA engines. Located in Fort Collins, CO 80524.
