You don't need to take any of the intake or the manifold off. I removed and installed the plugs, wires, and coils with a ratchet, extentions, and swivels.
14MM bolt to the bracket for the plenum next to the fire wall took a lot of time to remove then more time to reinstall. If you drop a socket or bolt and bounce around below the engine compartment good luck finding it.
My one question I had he literally said he didn’t know the answer to, and I’m stuck.. did my plugs, coils, and wires.. but my new set of wires are not numbered and I don’t know which wire goes to which coil.. please help ! 96’ Camry V6 1mz
