I have 171k on my maxima...other day i changed the oil and decided to check the plugs...and they are gone.

Which ones have you guys used, and what are the best for performance/mileage and interval.

I think i will get the laser iridium as that is OEM. But, what do you guys think ?

Thanks

 

NGK iridium plus 4's are pretty good only 8$ a plug I think thays what I'm going to use

 

NGK Iridium's (LFR5AIX-11) or you could go Laser Platinum (PLFR5A-11)

Most of the guys would most likely go with the NGK Iridium

 

While talking plugs, anyone tried those E3s??

 

I heard they(e3) were a waste of money. Not that they were garbage, just that the minimal difference they made wasn't worth the cost.

 

I have about 20K or more on the E3's in my car. They were cheaper than getting the NGK Iridium's so I thought I'd give them a shot. So far so good, but I'd like to get more mileage on them before I give them an official thumbs up or thumbs down.

 

The general consensus on my local site is "All of the "real life examples" always involved american cars. I'm not convinced they'd provide the same gains on a VQ".

I say stay with the proven spark plug for the VQ engines NGK Iridium's (LFR5AIX-11)

 

your best bet would be the NGK's I have them in my car =)

 

ngk for brand....

copper gives you stronger spark but less life.... but at 2 dollars a plug who cares....
Platinum gives a decent spark and a much longer life span...... more expensive for the set
iridium sparks better than platinum and lasts just as long.... even more expensive than the platinum

 

Thew some NGK Laser Platinum in mine yesterday when I changed valve cover gaskets. Marked improvement from the crap that was in there before...

 

I used ngk laser platinum in my last car and man was it good!

 

Yea ngk has been number one for lots of cars. Don't get cheap plugs cause you'll hit 5k and it will miss real bad go with the ngks way good product

 

NGK's Laser Iridium +2!

 

 

I always bought NGK for my cars. Had a Accord before, and always used the ZFR-5F11s. Great plugs.

I will def. get the Laser iridiums...where is the cheapest i can get them for ?

 

OEM.

 

I used to have e3's before. Switched to Ngk iridium and no difference. Just my 2 cents.

 

I have been using the Iridiums LX for couple years now on both maximas i owned, hands down the best ive used and worth the money i spent on them

 

anyone change spark plugs on a 3.5? i heard theirs one directly under the intake manifold. wanna change mines soon but looks like its gonna be a misson o_0

 

INtake Mani needs to come off. I still changed my plugs under a half hour. Search here under the DIY.

 

I'm curious about the kind of spark plugs that our cars need.

The FSM recommends the Platinum spark plug but another ones says that we can use the cooper type. The former owner of my car put cooper spark plugs (NGK brand) in her but I don't know how much millage they get and I know that this spark plugs last around 10,000 Kms (6200 miles) affecting the performance and fuel efficiency when the cooper ones begins to wear-out.

Maybe I'll go by the Platinum type even when they cost a little more.

 

I changed mine out at 90k with NGK # LFR5AGP (# 5018) G-power Platinum Tip. Changed them again at 160k with same plugs. Seem to perform well and the cost is low... $5-$6 each.

 

Going to buy the laser platinum...since it seems like a recommended product. I am not sure what is in there right now..but it seems like they are shot. Acceleration and gas mileage have dropped like no other.

 

Just bought laser platinum for $51 shipped !

 

That's a fair price I paid just over 60.00 for my plugs, you will notice the difference as soon as you replace your existing ones.

 

Just finished changing them out. It was a pain, but it didn't take me four hours, maybe 2.

After i started the car up, it seems like there a little rattling noise. ill make a vid. Idle is normal, smooth. Just a little raspiness when you accelerate. Seems like power is back. The old plugs were completely SHOT

 

NKG copper is what i use. $3 each and last 30k. spend the insane money on laser iridiums and platinums only if you plan to keep the car for another 100k. otherwise, its a waste of money

 

Devil's Advocate :
$36 for 12 plugs for a period of 60,000 miles for copper plugs

$45 for 6 plugs for a period of 60,000 miles plus another 40,000 before change for Nissan recommended iridium plugs

Even if I'm doing the labor myself, an hour of my time is worth more than 9 bucks. Not to mention the additional items I risk having to replace by changing the plugs.


Waste of money? You decide.

 

The former owner used cooper plugs but I just bought platinum spark plugs.

$2.5 (Platinum) vs $2 (Cooper) = Bye bye cooper, Welcome back Platinum!

Also, I bought the Bosch ones. And before anyone say it... Yes, I know that NGK it's recommended but with a long history in all the family cars using Bosch spark plugs (and 4 of them being Nissan) without any problem and a good performance I just stick it with Bosch.

 

Hey its not that big of deal to change out the the rear plugs. I did it tonight in about 1.5 hours. All you need for complete job.
12mm socket
10mm socket
5/8 spark plug socket
8" extension
Needle nose pliers
Allen wrench to remove cover

Really easy I thought it was going to be horrible also but not to bad
