Those of you who have not changed the spark plugs on the Nissan cube wanted to give some tips. Change at around 100k to 120K

1. use OEM Denso FXE20HR11 iridium spark plugs (Denso is the OEM brand Nissan used for the cube years 2009-2014) Found them on eBay for 4 for $13

2. The spark plug gap standard gap is ( .043), limit (0.55)

3. While your changing plugs go ahead and change the o rings on the upper manifold and the throttle body O ring. Got both as a set from Autozone for $18

4. According to Denso, the iridium plugs are good for 120K miles, I changed mine at 100900 the plugs still looked decent but I felt I was losing some gas mileage. so I changed it today.

5. Nissan cube doesn't use spark plug wires if you didn't know, they use Ignition Coil Boot, can get a set of 4 NGK brand for about $31 on eBay. After a 100K miles mine still looked really good so no need to change it.

6. It is about a 2-hour job unless you're a really fast and good mechanic, the spark plugs are hidden under the upper manifold. you also have to detach the throttle body and the intake or airbox whichever you have, I have a Takeda intake. Lots of screws to remove and few hoses to detach

7. It's really a pain in the ass, not like a simple Toyota just remove the engine cover and the spark plugs are right there, Nissan made it really difficult for a newbie to change the plugs on the cube.

8. In the US if you take it to a mechanic they will charge $200 to $300 for the work if you bring the plugs.

All cubes 2009-2014 are the same engine in the US
I hope that this helps some people since many cubes should be hitting 100k or more by now and will need spark plugs changed.
Also here is a video. I did not make the video please thank the youtube that did.

Just to let you know guys I changed the original plugs ay 100900 it could have gone another 20k possibly from looking at the plugs, What I did notice were a better throttle response and improved gas mileage. My mileage had been going down a few miles as my car approached 100k.
