Will I need an ECU reset with these aftermarket parts??
I was told that I would probably need an ECU reset to see and feel actual power gains with these aftermarket parts:
Nismo R-Tune Cold Air Intake, Nismo R-Tune Headers, Nismo Catback Exhaust System, 5/16 Motordyne Plenum Spacer.
Has anyone installed these aftermarket parts and had to do an ECU reset?? Or can I just directly bolt them on without having my ECU reset.

It's easy to reset the ECU. Just do it.
ECU Resetting Procedures
Timing is extremely critical. If it is NOT DONE within the specify time, the ECU will not reset and the Check Engine Light (CEL) will continue to remain ON.
A stop watch or an analog clock with a second’s needle will be useful.
Operations Procedures
1. Confirm that accelerator pedal is fully released, turn ignition switch “ON” and wait 3 seconds.
2. 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.
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 (The CEL light will continue to blink).
8. Turn ignition switch to “OFF” position and now you can start the car. The CEL light should be gone.
If the CEL light continues to remain ON, repeat the above steps. Timing is EXTREMELY critical to resetting the ECU.

Resetting the ECU is totally unnecessary in any situation. The fuel trims will not be relearned any quicker than they would without a reset.
Short term and Long term fuel trims are what adjust to compensate for new mods. They are constantly compensating for many other things as well. They fuel trim data they access looks like an Excel spreadsheet. Each block is updated after a certain amount of 'time' is spent driving in it.
For example, a block for 5000rpm @ 65% load is updated after you request info from that block x times.
An ECU reset will not change the number of times you must access any particular block, and will not change the outcome or speed at which the ECU adapts to new mods.
All resetting the ECU does is return all the fuel trim blocks to zero. You're actually better off not resetting the ECU as it most likely won't have to make as much adjustment.
ECU resets are an old wives tale and something that keeps getting spread around by misinformed "car guys".
Put the mods on, and the car will do the rest.

So the simple ECU reset solved your issues? Much thanks for the input everyone. Damn mechanics at the dealership are just trying to get me to bring in my car so they can rip me off for installation fees and a simple to do ECU reset. And in response to DAVIDV asking about who said I might need an ECU reset, well hes a mechanic at the Nissan Dealership in Totowa NJ by Rte 46, you probably dont know where that is. But anyways he said by installing the aftermarket parts its going to allow the engine to breathe easier but it will register as a fault, hence the ECU reset questions. Thanks to everyone that helped out .
.It ain't gonna hurt any, so give it a shot. ( make sure have your watch next to you.)
