The original intakes aren't that hard to do. Its basically unbolt the old one, clean up the surfaces, intstall new gaskets, put the intake back on, install bolts and tighten in the proper order to the proper torque. You will want to get a service manual if you don't have one to get the good step by step directions but thats the nuts and bolts of it. If you are competant with the wrenches you should have no trouble.
