Complete set of gaskets. This kit includes upper and lower gaskets, lower intake manifold o-ring and throttle body gasket. Everything was clearly marked and painted. Nothing to worry about. All seals and o-rings were installed without problems, nothing to change. A big plus, most parts are still made in the USA. The end result, you have perfect shape and professional results. It was worth it. I would never skimp on reassembling a critical component of my 1998 Ford Expedition. Especially when my whole family assumes they can get from A to Z safely. In addition, I was able to save a lot of money thanks to Revain.
