i would always stick with NGK plat. plugs. they are the best...

 

Does everyone agree?

 

Yes, NGK is very good spark plugs.

The only other spark plug I had experience with is Bosch platium (4 claw)..didn't think it was any better tahn NGK.

 

NGK

 

What about Denso Iridium plugs?

 

What about Denso Iridium spark plugs?

 

People seem to think copper plugs perform better. There real cheap so I am going to try switching to them once my car is repaired(MAF fouled my plugs).

 

I know in the LS1s we take out the stock platinum plugs as fast as possible and replace them with copper NGKs. I am not entirely sold on platinum plugs. What do you think NGK coppers?

Oh by the way how big of a job is it on the Maxima?

 

Look up one post

 

OK I did question answered.

How about my second question?

By the way I was just drooling on your website when you just replied. VERY nice Max!

 

Thanks

Question #2. That depends on how mechanicly inclined you are. The front 3 plugs are real easy to swap. The rear 3 are another story. At the very least the intake manifold runner needs to be removed. In all honesty it's easier to just remove the whole intake manifold. I expect it to take me about 45 minutes to do the plugs.

 

Will a new gasket be needed?

 

Copper is suppose to be better because it has less resistance (electricity can flow thru it better.) Platinum have more resistance but it last much longer, so it is the spark plug of choice for cars.....

Iridium is suppose to be less resistance than copper AND tougher than platinum.
So the best of both worlds?

Comments??

 

Copper plugs should perform better, but they will need to be replaced sooner... like after 30k miles

 

emax,
how do you know that the the plugs are bad due to the MAF?? my MAF went out on me a month or so ago, and i had it replaced with the newer MAF. i want to know if i have to replace mine also, without having to pull them out for inspection.

 

Fifty million years ago, an asteroid composed almost entirely of the precious metal Iridium (Ir-77) struck the earth creating the Gulf of Mexico. From this catastrophe came a metal with properties ideal for spark plug construction. Using this element, DENSO has evolved spark plug design to a new level. Using Iridium, which is 6x harder & 8x stronger than platinum, the tip can be shrunk to only 0.4mm. This means the voltage requirements are decreased while firing performance is greatly improved.

A bad MAFS makes the car run very rich, so rich that it fouls the plugs.

 

Denso Iridum and Ngk are practically the same. I buy Denso because they give you a great comparison on the box against leading spark plugs. I would recommend denso iriduim and Viteck wires! Just my 2 cents

 

Actually iriduim performs better, its like 50 times hotter than copper. Its proven!!

 

thanks man.

 

From what I have read, both Platinuma and Iridum last a LONG time; Iridium lasts the longest. I also have read that Copper may be a good option for NON-N/A cars.

I went with platinum on my 2000 and I did not have much trouble. It just took a while to finish. Is the install on the 2K2+ different than on 2K and 2K1's ?

 

Is the Iridium the plug to get then? Denso?

 

For what ?

 

If you get Iridiums, you MAY never have to change the plugs again. I have read estimates of them lasting up to 200K miles.

 

DENSO is the name brand of an iridium plug, just like NGK is the name brand of one too. I prefer DENSO though. In my opinon, that would be the plug to get.

 

http://www.rvmracing.com is listing them for sale ($68.99/set) but I am not sure if the part number (IK16-5303) is correct since they listed them for both 2k-2k2? FYI, NGK has difference part number for 2k & 2k2 according to Courtesy Nissan website.
