Changing Spark Plugs

Postby puddin' » Wed Aug 22, 2018 6:37 am

I am going to change the spark plugs this weekend on my wifes 2013 PF. It has 95K miles on it and I know the plugs are good to 100K. I already have the stock Denso iridium plugs. Does anybody have the FSM how to change them? or a link to youtube to change them? or any tips or suggestions before I get started. The front 3 should be easy, but I'm trying to make the back 3 changed as easily as possible. Thanks

First I let my plugs on my 2003 go though 145 kmiles.
They were in ok shape, no codes, and would have lasted longer.

You can find the FSM through 2016 at nico.
I dont have link handy. search, sign up and ask for link.
Nissan took legal action against them, and they took them down. but now you can access with a link.
But no new ones will be hosted.
BTW make sure you clip the coil conectors home properly, had problems with one of mine.

Stock plugs are usually NGK on any Asian make car, including Nissan.

The Denso's may work fine, but they are an economy version of the real thing...

NGK 1406 {#DILKAR7B11} Laser Iridium is the factory plug.

SMJ may have more info.

Actually, the NGK # 1406 is a factory equivalent plug. The factory plug is Nissan # 22401-EW61C, which is actually a Denso # 3442 (FXE22HR11) Iridium Long-life. I'm not sure why they made the switch because they've used strictly NGK plugs in Nissans sold in the US for as long as I can remember, although I know they have used Denso in some of the overseas Nissan models. Either is an excellent plug choice. Denso was once owned entirely by Toyota, but they became independent around 1950 and now Toyota owns about 25% of the company. Denso is the second largest auto parts supplier in the world and NGK is the largest spark plug manufacturer in the world. I'm a long-time, die-hard NGK and NTK fan, but Denso is right up there with them in terms of quality and both seem to work well in Nissans and anything else they are put into.

I am about to have mine replaced at the dealership. So there are no plug wires to replace? Should the coils or anything else be replaced when I replace the plugs?

No spark plug wires on Nissan VQ engines. Unless an ignition coil is bad, I wouldn't recommend replacing them. I replace the intake plenum gaskets when I do mine, although, technically, they can be re-used.

Thanks for the information. It really helped me!
