For those of you that have changed the spark plugs on the 2k2's did you install a new intake manifold gaskets? I am thinking I will just to be safe, but I was just wondering what everyone else did.

 

The manifold gasket is made out of metal. No need to replace the gasket. I didn't.

 

Just curious but why would you change your plugs. They are made to last at least 80k

 

nitrous? might need one step colder copper plugs for that... i'm looking to change my spark plugs once i get my nx kit in.... i hear it's a ***** and a half to do.....
CBass69187 : let me kno how it went... i might need some pointers on how to do it....

 

I've been having detonation problems and wanted to do it anyways. The longer you have your plugs installed (over 80K) the harder they are to remove (so I've been told)

Here are my old ones

 

maximadave..u got any shortcuts on removing them?

 

KiLLer2002se actually helped me out since he had the tools. After I tilted up the manifold I saw my valves which looked pretty clean. Unfortunately I didn't have my digital camera with me

I thought there was a sticky on replacing these....

 

tools will be no problem... a buddy of mine is a manager of an auto shop... and i have access to basically anything i need..... but even with all that i heard it's still a pain to do....

 

It took us about 2 hours to do.....wasn't too bad

IDid you use the NGK's?? If so, where did you buy them from?? Does anyone know of a good deal on these??

 

[QUOTE=VMosser323][QUOTE=maximadave]I've been having detonation problems and wanted to do it anyways. The longer you have your plugs installed (over 80K) the harder they are to remove (so I've been told).I bought them from a distributor down the street from my house. The prices are pretty good there. Here is his link.

It was a pain for me the first time i did it because I seperated the manifold from the throttle body, there are some PITA connecting those things together. Leave those bolted together and just take the manifold off. There are also two bolts behind the manifold connecting to the throttle body for extra support, those need to be taken out. Its pretty simple once youve done it 10 times

 

Thanks guys !!!

 

maximadave: So did you go to a colder plug? I've noticed some mild detonation even w/ 92oct. with our '00 maxima.

 

That could be caused by your coils. There is a TSB on it and your Nissan dealer should replace them. I went with NGK Platniums, basically the Nissan OEM replacement.

 

did you guys have to regap the new spark for your 2002. I got the ngk LFR6A11 (for nitrous). Do I have to regap them or put them in the way that they came?

 

NGK says they are "pregapped" at 44 but measuring them, they were only at 40. I had to regap them. No biggie

 

thanks maximadave

 

what are u gapping the plugs to and on what shot
