Stock B Series Cummins air to water aftercooler for sale. Bought it new for high dollar. Ran it for two or three dyno runs. It's still like new and painted Cummins beige. Looks brand new. It's been stored inside waiting for me to decide whether or not going back to it or to use it for a different engine. Decided to sell to fund other projects. Price is $300 plus shipping. This style aftercooler will require the aftercooled style injection lines available from Cummins or Case/IH or custom oversize lines bent to fit.
