I can't seem to do a search....
actually, my search function ain't working for some reason, is this normal?

Anyways...back to the problem. I wanted to change sparkplugs on my 2k2. the local autoshop said they needed to take the intake manifold out for the back two plugs so they need gaskets. I told my nissan dealer the situation and they were like 'wtf? u don't need to change them until 100,000 kms, and we never changed one yet!', so they have no gaskets for that kinda operations in stock. In the end, they order a gasket, but the autoshop said its the wrong gasket.

So...is changing the plugs really that difficult?? And can anyone tell me what exactly do I need to get it done???


Thanks in Advance

 

why do you want to change them?

 

Here is the information on changing spark plugs from the 2002 Maxima Electronic Service Manual:

---

Tool(s):
- 16 mm spark plug wrench with a magnet to hold the spark plug.

1. Remove intake manifold upper and lower, collectors.
2. Disconnect ignition coil harness connectors.
3. Loosen ignition coil fixing bolts and pull out coil from rocker cover.
4. Remove spark plugs with suitable spark plug wrench.

Spark plug (Platinum-tipped type):
Make - NGK
Standard type - PLFR5A-11
Hot type - PLFR4A-11
Cold type - PLFR6A-11

Use standard type spark plug for normal condition.

The hot type spark plug is suitable when fouling may occur with the standard type spark plug such as:
- frequent engine starts
- low ambient temperatures

The cold type spark plug is suitable when spark knock may occur with the standard type spark plug such as:
- extended highway driving
- frequent high engine revolution

Gap (Nominal): 1.1 mm (0.043 in)
20 - 29 N·m (2.0 - 3.0 kg-m, 14 - 22 ft-lb)

Do not use a wire brush for cleaning.
If plug tip is covered with carbon, spark plug cleaner may be used.
- Cleaner air pressure: Less than 588 kPa (6 kg/cm2, 85 psi)
- Cleaning time: Less than 20 seconds

Checking and adjusting plug gap is not required.

Hope it helps. Peace.

 

Yeah, why would you wanna change them? You don't need to change them until you have 105,000 miles.

 

eh, not really. i changed them when i had 60k on my car and what a difference. the car runs smoother, accelerates faster, and a lot better MPG

basicly...i would do something like this every 40k

 

I'm changin them to Denso iridium...that's why.........

thanks for the info, especially 01SE02SER...
so if u are removing the intake manifolds, u DO need a new gasket when putting it back right?

 

Logic would say...

Gasket = 10-15$

Intake manifold leak = ???????????? x $$$$$$$$$

If you really want to see a car run like shiznit, have a vacuum or intake manifold leak.

 

Jason, I am looking for you bro... Ck your Email, PM and this thread. Fed Ex called me to say they've been trying to deliver the box for 3 days with no luck. They are threatening to send it back to NYC. Get in touch with me .. man...

 

I got back to you ralph, check email. Thanks...
so, I don't mind paying for the gasket...but anyone know which one or part #? I hate asking Nissan cause they will ask stupid questions and give smartass comments.

 

I thought about changing mine early too. I hear that when a spark plug has been in for 100K that they are a pain too break loose. Anybody have a problem with this?

 

For those not inclinded to do this job themselves, the Nissan coupon in the mail is $74.95 for all six changed...
