What Spark Plugs are the best for the Maxima???

NismoMaximaGTR · 03-10-2005, 05:06 PM

I'm getting crappy gas mileage and need to change out my Spark plugs. I have a 98 Miaxima with 120k miles. I heard the NGK plAtinums are the best for the Maxima. Any other opinions or experience would be appreciated, Thanks in advance.

I agree I had myh plugs changed two days ago. And they reccomended me only NGK's. So I got factory plugs and got them in. The guy I bought my car from never changed them so when the plugs came out... they were all rusted. NGK's will run you 60k. USE NGK.

Thanks for your help guys. That was my first choice, but I just needed some input to make sure is was the right choice. Thanks again.

im running ngk iridiums, working perfectly for me

*jblinga* · 03-11-2005, 03:01 PM

Bosch do not run well in maximas like luvs2speed said, go w/ the stock plug for best results ngk platinum

*Zeus97MAX* · 03-11-2005, 03:02 PM

NGK Plats are what the manufacturer puts in the car. If you look at any manual for the max, they all say NGK Plats for replacement. Anything less would be uncivilized ha!

INDEEEED!!!!

maxima_kenny96 · 03-11-2005, 04:11 PM

NGK seems fairly good thats what I have noticed alot of ppl using but im sure there are other brands out there that are really good also I doubt u HAVE TO USE those.

*questwest* · 03-11-2005, 04:25 PM

I have had Bosch Platinum 4+ in for more than 10k now and it runs perfect. Very good mpg and performance wise no problems at all. bought it online for 28 bucks.

*maxgtr2000* · 03-11-2005, 05:32 PM

I'm running ngk iridiums, noticeable power increase, but I feel increases after oil changes too.

Bobo · 03-11-2005, 05:35 PM

So which are best: Platinums, Iridiums, Copper - ignoring cost considerations.

DragonMaxima · 03-11-2005, 10:53 PM

Iridiums, Plat, Copper

MaDMvD · 03-11-2005, 11:02 PM

I'm running NGK Iridium IXs as well. Nice plugs, paid ~$37 shipped on eBay for all 6.

*1FSTMAX* · 03-11-2005, 11:09 PM

bkr5e.......

Luvs2speed · 03-11-2005, 11:40 PM

I dont stick my **** in anything without a condom....I wouldnt put plugs in my max unless they were NGK PLATINUMS.... PERIOD....no bosch, no nothing....anything else in time will damage your engine internals....questwest your crazy for running bosch man-I cant believe you dont have any probs...call the dealer and tell them what your using, see what they say

*SPiG* · 03-12-2005, 01:36 AM

Go with NGK coppers. BKR5E-11 if stock or bolts ons. Make sure they are gapped to .0433in or 1.1mm because sometimes they can be gapped wrong out of the box.

Iridiums are the best performance, then Coppers, and then platinums. Platinums last longer but are much more expensive than coppers. Iridiums are mainly for boosted or nitrous people. They are the only people that would notice anything really different performance wise over coppers.

Once again NGK ONLY!!!!

Ive heard horror stories from several mechanics saying bosch +4 causes the oem coilpack to spike and fail prematurely. ...no worth it for me

ditto with the iridiums... also, if your gas milage has gone down, clean or change your air filter depending what setup you have. I noticed when my milage went down, I changed the plugs, oil, and feul filter, it was still not getting as much milage as before, but it was running smooth though, and when I cleaned filter, voila..

*maximazation* · 03-12-2005, 04:15 PM

speaking of cleaning air filters, i have an air filter that i baught my car with, and it has the rubber around it colored orange and has a metal grill on the filter itself, is this is a fram? and is it reuasble, as in washable or reoilable?

suicidalspd99 · 03-12-2005, 05:36 PM

i run the denso iridiums. they do just fine.

G4nismo · 03-12-2005, 09:06 PM

i just replaced mine to NGK vpower copper. got 6 for $10 at advance.

friend and i did them under an hour. he was really disappointed cause he wanted a challenge. anywayz, car runs great.

*d00df00d* · 03-12-2005, 11:50 PM

Okay... I have to ask....

What the heck is the big deal with never using anything but NGK plugs? What makes them so special?

There are laws about merchantability that state that you can't sell something if it causes unreasonable harm... I could see how Bosch and Denso plugs might theoretically not work as well, but how the heck could they cause damage to your engine?

Bobo · 03-13-2005, 08:37 AM

Why don't you put them in and find out? If a friend told you not to jump off a cliff because you might kill yourself, would you do it just to find out, lol?

Heh, that's what I thought. I've been running Denso Iridiums for almost 6.5k miles and they've treated me nicely so far.

But.... there has to be a reason why everyone kicks and screams about NGK plugs. If there isn't, I'd love to expose the false rumor....

Bobo · 03-13-2005, 09:22 AM

Then you might as well run 87 octane and the crappiest oil you can find because after 6,500 miles you might not notice any problems either!

*Batxel* · 03-13-2005, 09:27 AM

when I bought my max, I changed my spark plugs to NGK plats, there were denso plats in there... How are denso's?

Luvs2speed · 03-13-2005, 09:39 AM

doodfood...the reason why you have to use NGK...bosch and all the other plugs are bad for your coil packs....the other brands create the wrong kind of spark needed for your nissan maxima...your coil packs will fail faster with the use of bosch and etc...do you know how much coil packs cost??.....use NGK plat or copper....how can you debate the FACTORY OEM NISSAN PLUGS!!!!!!!!!!!!!!!!!!!!!!!!

*MaximaSE96* · 03-13-2005, 10:35 AM

i ahd a bosch platinum break in the cylinder head of my 91 SE.....the electorde broke off and shot into one of my injectors.....never again will i use anythign but NGK Plats.....

either!

Good point. But the thing is, I can tell you exactly why those things are bad:

87 octane fuel:
- Increases the chance of knocking because it's easier to ignite
- May lower fuel economy because you get less energy from burning it

Crappy oil:
- Doesn't lubricate as well in general, causing more wear
- Doesn't maintain its characteristics well over a range of operating conditions

These things are common knowledge. On the topic of spark plugs, though, I just haven't heard actual explanations of exactly what it is about Denso and Bosch plugs that makes them unsuitable.... just a bunch of claims that it will bust your engine.

Same reason people debate the factory intake, flywheel, exhaust, clutch, etc.... because if I can, I want to make it better.
