The Edelbrock Ti-Tech Coated Jeep 4.0L header comes with everything you need to install it. The kit includes the header, a new intake/exhaust manifold gasket, a new donut gasket for the downpipe, new hardware for the downpipe, and a set of very complete and detailed instructions. The first step in the installation is to remove everything that is connected to the intake manifold with the power-steering pump being the first thing. Loosen and remove the fan belt, then unbolt the power-steering-pump bracket from the intake manifold. You can leave one bolt in the block and just lower it out of the way to give you the room you need to work.
