Modifying BasisSportTony's directions slightly:
Note 1: removal of the cowl may make it easier to access the 2 rear most bolts(step 5), but is not necessary at all.
Note 2: Prior to tear down/install, inspect the new manifold for damage (cracks, etc) and/or obstructed ports (vacuum line). *ahem*
Tools: 12mm, 10mm and possibly 6mm sockets with ratchet and extension
Phillips screwdriver
Flathead screwdriver or nut driver for hose clamps
4mm hex key (if you have the K&N Typhoon intake)
Pliers (I used a 90 degree needle nose)
Ok, start from the right and work left:
1. Disconnect the MAF sensor. Remove your stock or cold air intake, just the tube leading to the throttle body may be enough (6mm socket and 10mm socket, screw/nut driver, 4mm hex key).
2. Disconnect the sensors that are attached to the manifold/throttle body. Unbolt the Purge Joint bracket. This will just hang free with the Fit manifold installed unless you come up with something custom.
3. Unbolt the throttle body (12mm Socket 4 bolts).
4. Remove the bolt between the throttle body and the valve cover (12mm socket).
5. Remove the 2 bolts(10mm, iirc) that hold the manifold to the mounting bracket (towards rear of engine).
6. Remove the IMA manifold cover by just pulling up on it. This will NOT be re-installed on Fit manifold.
7. Remove the 5 bolts holding the upper intake manifold to the lower aluminum manifold (12mm socket).
8. Remove the upper manifold/plenum. Push away from you slightly as you pull up to clear the 2 alignment pegs.
9. Before walking too far away disconnect the brake vacuum line from the rear of the manifold. Use the pliers to loosen and move clamp and a strong and steady pull by hand to remove the vacuum hose.
10. Once the manifold is off peel off the rubber gaskets and put them on the new
manifold. Or use the new ones from the kit that you may have previously ordered (recommended, not required).
11. If the Fit manifold didn't come with the MAP sensor, remove that from the CR-Z manifold. This might be the hardest part, the Phillips screw is on pretty tight. Loosening it up when the car is warm and then working on the manifold after it has cooled down might help. Install on your new manifold.
12. To install new manifold, Start at step 9 and work back through to step one.
I suggest snugging up the 2 bolts from step 5 before tightening any of the rest for ease of alignment. Consult the torque spec graphics found elsewhere in this thread.
Double check electrical/sensor connections. *cough*
It really is only 30-45 minutes.
