very easy, only special tool you need is a fuel line disconnect tool (there cheap). there is no coolant that runs threw the intake so there is no mess involved. it does probably have one small coolant line that runs threw the throttle bottle, very little coolant will be lost tho. hardest part is probably fishing the intake out from under the harness, and thats still easy.. just make sure you use compressed air to blow around the intake before you start working to prevent debris from entering the motor. gaskets snap onto intake which make install easy as well. after intake is removed just use a razor blade to clean surface, vaccum anyleft over debris. wipe down surface with some brake clean and its ready for install. don't quote me but im pretty sure theres ten, 10mm head bolts that hold them on
