About 3 months ago i installed Champion copper spark plugs in the Maxima.

I just had a question (sorry if it's a little noob -ish)

Do the type of spark plugs actually make a difference in power/fuel economy? I recently heard that NGK spark plugs are what im supposed to put in the Maxima, and that Champion plugs aren't good enough for her. Can anyone give me their imput on this? should i change them out for NGK's, or even some other brand i dont know about?

Thanks a million
Joey

 

Stick with the NGK's. They are well worth it for making the Max run like it should. Putting in any substitute will only cause more aggravation and problems. I know the NGK's are pricey, but if you try cheaper replacement plugs, you'll end up paying for it by having your car run like crap. Don't skimp out on this simple maintenance. Put in the NGK's and your car will definitely be glad you did.

 

for the post above!

 

Ditto.... Use NGK

 

NGK ftw! make sure its the Double Platinum NGK plugs not the copper plugs or anything else. but yeah you will be glad you did as mixxmax said, and they last so much longer anyways.. well worth the money

 

yeah.. i just put NGK's in my car a little bit ago after 88,000 miles and i could really feel the difference in performance.. they're the factory plugs and best 4 the car

 

I will 2nd NGK plugs...they can be bought for cheaper...at www.pinnaclenissan.com

shipping is a flat rate $7.75

 

NGK Irradium for 10000km... didn't feel any difference with OEM

 

I should probably check to see if I need to replace mine. I am at 53k miles.

Is replacing the plugs an easy job or should I just find a shop to do it?

Thanks for any info.

 

I did mine @ 65k. There's a write-up in the stickys.

 

Yea, I found sources that show how to do it but I was asking if it is recommended to take it to a shop. If it is not too expensive then I would rather just take it to a shop. Thanks

Also is this the cheapest place to buy the OEM plugs.

Thanks.

 

so what is the type for an 02 6spd NGK brand?

 

The part # in that link is the wrong part # for 3.5L plugs.


You can use the same plugs as an 03 Automatic would use. I used LFR5A-11's (copper)

 

Is there going to be any difference in the procedure from the write-up when changing the plugs on a 2000?

 

So if I get a tune up with my local nissan shop, they will replace them with these spark plugs?

 

Yes there is a difference

They will use the correct ones.

 

quick question... wat do u think about the ngk iridium... same price as the platinums... and the iridium is safe to use with nitrous... not like i have it but its supposedly 8X stronger than the platinums and have a higher melting point of 1200 degree Farenhiet... im just curious to know... heres the specs
NGK Iridium plug 7994 IFR5E-11 0.044 DOHC $11.71
NGK IX iridium 5464 BKR5EIX-11 0.044 DOHC $6.95
NGK Double Platinum 2647 PFR5G-11 0.044 DOHC (Original Equipment Manufacturer, and/or Original Equipment Service Part) $11.71

and i got this info from sparkplugs.com

 

Changing plugs are much easier on the 2k-2k1 models. It doesn't involve much complication procedure like the 2k2-2k3 models. For the 2k-2k1 models, just remove the valve cover to access the front 3, and for the rears, just remove the coils to access the other 3. There may be some blocked access for the rears, but it's not that complicated. You just need to get around the throttle cable.

 

I would stick with the NGKs

 

Ok, excellent. Thanks.

 

2001 GLE 132K miles auto...
Just completed a fluid flush upgraded to drop in K&N filter and changed out spark plugs to new OEM plugs.

Did a trip to CLT from JAX... at a constant 70-75MPH got 26-28MPG...

I would say... stick with OEM.

 

whats the model number for the stock ngk plugs that go on the 02-03?

 

I know what you meant, but to calrify, it's an engine cover, not a valve cover.



Reading the stickys > asking.

 

i'm at work and would just like a quick answer. Im not asking any1 2 look for it im just asking any1 that may know it out of there head or got it around there desktop written somewhere. If no1 knows it I'll just look it up later myself. In forums ppl help out each other not just refer to a sticky. What is nice, are the ppl that send you the link to sticky. Now those are helpful ppl, thats where my thanks go to jime, irish, and sooner.

sorry for the slang but im at work like i said

P.S y the hell are ppl on this forum so **** about stuff

 

ngk all the way

bump... sorry i know its on someone elses thread didn't think it was a bigg deal for me to open up a new thread... just curious since i am currently in the market for new spark plugs

 

Get the Iridium geez.

 

thanks alot i was stuck with the same choice, iridium or platinum i thik i'll go with iridium now

 

Use [B]NGK,[/:B] I learned the hard way

 

Everone i know is a mechanic. My dad, uncles, cousin. and everyone says use the ones that are supplied with the car. Chevy uses ac delco..replace with ac delco, ford uses autolite.. replace w autolite, lawn mowers and tractors use champion... replace w champion. Pull the champions and put ngks back in. Much better than the champion .. at least for the max. I use only ac delco in my camaro i just paly around wth the temp of the plug ( hot or cold).

 

Stick with NGK I know a bunch of people that have had problems with other brands espectually bosch.
