DISCONNECT THE BATTERY FIRST!

This would be great time to change the spark plugs as well.

Remove the upper intake manifold. Once the manifold has been removed it will look like the picture shown below:

STOP EVERYTHING! PLACE RAGS INTO THE CHAMBERS.

If a bolt is dropped into there you have big problems.

Using a 6mm socket , remove the intake studs on both sides

Using a 3mm allen head bit install the new intake studs provided with the kit

Proceed to the two hoses that were removed from the throttle body. using the brass hose mender join the hoses as shown to perform a throttle body bypass. this will help in removing unwanted heat produced from the hot coolant out of the throttle body

Due to the increase width from the spacers the rear manifold stay bracket must be removed using a 12mm socket and ratchet

Using a 12mm socket remove elbow and stock gasket from the manifold

Apply the thickness of a nickle coin of rtv gasket maker to both sides of the elbow spacer and reinstall using the 4 hex head bolts and lock washers provided in the kit.

Move on to the throttle body spacer

Using the white caps provided in the kit , cap off the 2 metal pipes going into the throttle body as shown

Using a 5mm allen head bit , remove the throttle body from the elbow. do not touch the valves on the throttle body. this will cause a idle malfunction and check engine light that can only resetted by the nissan dealership.

Remove OEM gasket and apply the RTV gasket maker to both sides of the throttle body spacer. reinstall using the allen head bolts and lock washer as shown. remember the location of the bracket that was removed from the throttle body

Onto the main manifold spacer

Apply RTV gasket maker to both sides of the spacer and center the manifold onto it. the intake studs will guide you. using the 3 hex bolts and lock washers tighten the manifold.

Reuse the oem intake stud nut and apply them onto the new intake studs on both sides

Check that everything looks as shown

Wait 45 mins for the RTV gasket maker to set.

Reconnect all the hardware and connectors that was removed to uninstall the upper manifold.

Reconnect the battery.

Peform an ECU Reset by following these steps

1. Turn ignition switch on and wait about 3 seconds.

Repeat the following steps (2a and 2b) procedures quickly five times within 5 seconds.

2a. Fully depress the accelerator pedal (HARD).
2b. Fully release the accelerator pedal.

3. Wait 7 seconds, fully depress the accelerator pedal and keep it for approx. 10 seconds until the CEL starts blinking. (here is where i think you can get a code from this.)
4. Fully release the accelerator pedal (while the CEL is still blinking)
5. Wait about 10 second.
6. Fully depress the accelerator pedal and keep it for more than 10 seconds.
7. Fully release the accelerator pedal
8. Turn ignition switch to “OFF” position and now you can start the car.

Perform an idle relearn by follwing these steps

Make sure that accelerator pedal is fully released.
Turn ignition switch ‘ON’ and wait at least 2 seconds.
Turn ignition switch ‘OFF’ wait at least 10 seconds.
Turn ignition switch ‘ON’ and wait at least 2 seconds.
Turn ignition switch ‘OFF’ wait at least 10 seconds.
Perform “Throttle Valve Closed Position Learning” .
Make sure that accelerator pedal is fully released.
Turn ignition switch ‘ON’.
Turn ignition switch ‘OFF’ wait at least 10 seconds.
Make sure that throttle valve moves during above 10 seconds by confirming the operating sound.
Start engine and warm it up to normal operating temperature.
Turn ignition switch ‘OFF’ and wait at least 10 seconds.
Confirm that accelerator pedal is fully released, turn ignition switch ‘ON’ and wait 3 seconds.
Repeat the following procedure quickly five times within 5 seconds.
Fully depress the accelerator pedal.
Fully release the accelerator pedal.
Wait 7 seconds, fully depress the accelerator pedal and keep it for approx. 20 seconds until the MIL stops blinking and turned ON.
Fully release the accelerator pedal within 3 seconds after the MIL goes off.
Start engine and let it idle.
Wait 20 seconds.
Rev up the engine two or three times and make sure that idle speed and ignition timing are within the specifications.
If idle speed and ignition timing are not within the specification, the result will be incomplete.

Enjoy
