Hi! I want to buy NGK spark plugs for my Max, I've read people use this: BKR5E-11 but can't find them on the NGK web site, however they show this:

Standard BKR6ES-11
V-Power BKR6E-11
G-Power BKR6EGP
Laser Platinum PFR6B-11
OE Laser Iridium IFR6E11
Iridium IX BKR6EIX-11

I'm confused, which one is the one you'll recommend is the best for the Maxima, the V-Power?? or Iridium?
Right now I have installed the Bosch Plat +4 (I know ) and I want to get rid of those, But I don't want to do the same mistake, please point me in the right direction. BTW is it worth it to buy the NGK spark plug wires? it really makes a difference or not? right now I have a cheap ones that I bought at AutoZone. Thanks!

 

I'm using : Iridium IX BKR6EIX-11

When it comes to spark plugs for Jap cars, always stick to NGK. They're the finest.

Got it from http://www.clubplug.net/ I'm planning on leaving it there for 100K, so far I've got only 30K. However, I think they can go higher than that...probably 120K?

 

damn I didn't know they got Laser Iridium too!! That's hot stuff man... that's my next move.

 

I have the Bkr5E- 11. I switched because the BKR6E's were running like crap. They are available everywhere - pepboys $1.90 a piece, part no 6953 ( they are also called v-power). If you run short distances and stop and go this is the preferred spark.
If you are racing, or going long distance, then maybe the BKR6E or something more sophisticated.

 

same I am using Iridium IX BKR6EIX-11. and they were worth every penny

 

bvtran, heresmymind: does it matter the use of the car like jimbo said? because most of my driving is stop and go / city driving.
When I mentioned I couldn't find the BKR5E-11 I mean the NGK website doesn't show in the list of spark plugs for our cars.
What Spark Plugs do you had before the Iridiums? V-power? Do you really notice a boost in performance?
Thx

 

some junky copper heads.... I replaced them with iridium and have been using them since then. Iridium is the best all around... no matter how aggressive or passive you drive. AC Delco warranted their iridium to 100K so I don't see why couldn't NGK last that long. I'm leaving mine in there 100K.

now as far as performance goes, you can't really tell when both types are brand new. However, copper head will burn off quickly comparing to iridium head. What you get is longevity, reliability, and an extra peace of mind while driving long distance with Iridium.

 

buy it from that Canadian seller I recommended... see link above. I'm not sure what his problem was but he used sell NGK Iridium for $4/plug and now it's $6.9... either way, it's still 50-75% cheaper than your local auto stores.

 

Yeah! I just checked and it's 6.90 a piece plus S/H around $48 total, I think is worth it, anyways I heard (some time ago in a different thread) due the age of our cars we shouldn't leave spark plugs for over 20-25k no matter what the manufacturer says, I don't know I think everything is meant to last taking care of it and a good maintenance. Thanks man! I'll be buying the Iridiums in a couple of days.

 

I dont remember which i was using. but my car was sputtering and i couldnt figure anything out. when i pulled the original plugs they looked decent. but after I swapped them with the Iridiums it was like day and night diff. so to me i like them. if there is a major gain compared to V-power i dunno.

 

There is no power gain with diffrent plugs, iridiums just last longer.

Quoted for truth. Same with platinum.

I use NGK coppers (~$2 each) and I get close to 30 mpg and run in the 14s at the track.

I would rather replace the plugs a few extra times instead of waiting for the slow death of the platinums. Besides, they always look nice and new.

 

well right now i myself am running bosh platinum +4's and have no problems with them what so ever getting good spark. as far as i know i am anyways wont know till a few days when i get my car on the ignition scope at college to see my spark pattern.

 

i have the V-power.

i think they are 1.79 ea at Autozone and 1.89 at Peppie B.

 

Platnum +4's are for ricers. They are worse then any regular 1 electrode plug.

~Alex

 

I used BRK4E-11. But that's just for the track while on race fuel.

On the street, I use Iridium IX in 5 heat range just b/c I got a killer deal on them. Something like $25 for 6 of them on eBay.

 

umm ok this coming from a VG maxima owner. enough said.

also did you ever start to think that maybe the platinum +4's last longer cause of the 4 electrods it has instead of one single electrod the normal plugs have so in turn these plug can be used up to 80,000-100,000 miles this coming from my teacher in auto tech who happens to be a master tech for both bmw and ford. so yes question me on why i use platinum +4's again. only reason i have them at this moment was because i didnt have the time and money to get the NGK's i wanted and the car was in dier need of a tune up.

 

Actually, I talked with a Nissan Tech (one that was on this site, I believe he owned a 5th gen) about Bosch plugs. He said they didn't work well with the coil packs used with the VE30DE engine and he believed it was potentially one of the reasons some VE owners have had troubles with stalling and bucking. He said he had seen an unusually high number of coil pack problems on cars that came in with Bosch plugs. He didn't say anything about whatever style (+4 or whatever) just that they were Bosch and he would only be using NGK on any Nissans with coil packs.

 

i know bro but i have had no problem with the plugs in my ve and also i do plan on getting the NGK's i want but when i get money till then the bosh will stay in anyways anything goes wrong i can fix it more aless since i dont pay for labor at auto tech class i do all the labor or me and a few friends and yeah juz cost of parts. right now ive been learning about ignition systems and have traced all wires involved in the ignition system on the VE's trust me this car is loaded up the but with wiring for the ignition system it has. lolz even my teacher was amazed with the ignition system in my car since he has never dealt with a coil on plug photocell car being as bmw and ford really dont use that type of reference sensor.

 

It's not a short term problem, more of a long term one. Your car may run fine now or maybe for a year or several, but it could potentially lead to coil pack problems.

My car's coil packs were fried (2 fronts cracked and one rear was bad) and my brother had put in Bosch platinums at about 80k miles. I bought the car from him with 146k miles and he gave me a good deal because it kept stalling and bucking on him. His "great" mechanic (a 20 year Toyota Tech) couldn't figure out the problem and he spent hours trying to diagnose it.

Several of us brainstormed on this board years ago and I think most people have it figured out. Do a search in the 3rd gen forum on "stalling" or "bucking" and you will find lots of info. It is not always caused by the spark plugs, sometimes, the coil packs just go bad, even with the original ones in there.

Let me put it this way: new copper NGK spark plugs will run maybe $15 total for a full set of six. New coil packs are about $60 each ($360 total) if you shop around and get a good deal.

It takes maybe 20 minutes to replace 6 spark plugs if you don't rush.

 

Exactly. That was before bosch did the stupid multiple electrode pulgs so it was the regular bosch plugs. 87% of the world's OEM manufacturers use NGK, so they are designed for their plugs. They are similar and yet diffrent, and for COP cars like the VE and VQ it can cause long term problems.

Plus the 2 and 4 electrode plugs are retarted because they block the spark, especially with the 4.

In fact what happens is the plug ignites the fuel/air next to were the spark happens, and with normal plugs there is a lot of a/f around it. With the bosch plugs, theres more metal surrounding the plugs, making the flame front spread slower. This is fact, please discuss this with guys trying to make power. This will cause loss of power.

Plus the extra miles comes from the actual iridium or platinum the plug uses, not how many electrodes there are.

Also Colombianmax tells me there is a pending law suite about the +2 and +4 plugs breaking off in the engines and causing damage. I remember hearing something about it but we'll look that up later.

Any way have fun with your expensive, fragile and week (hp wise) plugs. I'll stick to NGK's.

like i said im not worried about it because soon i will be getting the NGK's i want and plus rebuilding a motor wont kill me since its part of my competancy tests i have to do to pass my auto tech classes plus i dont plan on keeping the block stock. i plan on buying a spare block and rebuilding it and building up the block internally. So like i said its not effecting me now or has it in the past the hp in my maxima is still there and has been in my previous one that i also put boch platinum plugs in. Also i took the plugs out last night at college to preform my compentancy test on compression and the plugs where juz perfect so far and i cleaned the even burn from normal performance but the coils are cracked on 3 out of 6 of them but i will be buying new ones and replacing them. Also if the bosch where as u call them bad and what not why are they still in mass production and being sold.

 

I have a spare block you can have for free, but there is NOTHING but the block. No pistons, crankshaft, etc. I took every single piece off of it.

The Bosch don't have a problem with normal distributor systems, just coil-on-plug. It's also not a problem that happens instantly like some explosion. It happens over time.

There are a lot of things out there that are crap being mass produced and sold.

 

did you ever wonder why no automobile manufacturer installs +2 or +4 plugs in the car from the factory?
it's because they are BS.
electricity always takes the path of least resistance, only 1 path not 2 or 4.
Food for thought

 

bro i know about that. That they only still will only choose one electrod and not all of them or 2 or 3 of them this ive learned in class.

 

I ran bosch platinums in my car for 60,000 miles with no problems at all...

But have since switched to ngk coppers,i just think it's better to change plugs on car with 200k+ miles on them more often so you can check for other signs of wear,like oil on plugs/specks on the polcelain[sign of detonation]/black soot[rich condition] etc...

 

Ahahaha. Thats funny. Ive 5 speed swapped my maxima, pulled engines, swapped suspentions etc. Ive probably worked on and owned more cars then you so w/e. Just because I own a maxima doesn't mean I don't know my cars. YOU were the one asking Q's any way...

~Alex

(PS forgot to reply to this earlier, I wanted to get my 240sx done, I was swapping the lower control arm. It took about 1:45 with a parts run to buy a tie rod)

 

Yea bro, we were workin on his 240..btw NGK ftmfw we love t3h rice

 

elusivemax93-I just heard from my aunt that her plugs snapped off and ruined her engine. Its an 87 bmw. I can't remember what plugs I put in but they were probably bosch's. only a few thousan miles on them too...

~Alex

 

hey i own a vg. so why dont you go in heck... i mean JK

 

its all good say what you all want too and also hey cliff so u said i can have the block? It is the ve block right?

 

Dude your signature is ****in huge!! made my window bigger so now I gotta scroll left.

Make it smaller like this

\/

 

Yes, I have a VE block. You can have it for free, but I am not sure how to get it up there.

LIke I said, there is NOTHING with it. I took almost every single nut and bolt off of it. I have quite a few of them lying around, but nothing significant. Oh, I think I have the chains still. I sold everything else (pistons, heads, crankshaft, etc).

 

Cliff thats cool man i juz want the block i can builds it up from there over time as i dont plan on having it all done quick fast and in a hurry. as for getting it i dont think it would be real soon unless i could get a friend of mine to drive down to oreagen and pick it up but if i do find some time between my college quarters and have the money to get out there and pick it up i will let u know when im coming if thats cool?

 

No problem. It is still on an engine stand sitting in my garage. If you get time in the spring or summer, I could meet you in Portland.

I am planning on going to Golden Gardens, but I don't have anywhere it will fit in my Maxima without removing my sub and I am not going to do that for a long trip like that.

 

Hello! I just received the plugs I bought online and they send me different ones, I got 4 BKR6EIX-11 (3764) and 2 BKR6EIX (6418) they look both the same but I don't feel comfortable installing 4 from one number and 2 different, what do you think, will this hurt the car? what are the difference between these two, actually the 6418 doesn't show in the list for plugs to our cars, please provide some advice because I don't know if I should RMA these or not. Thanks!

 

the difference between the 2 is the gap. regap the 6418s to .044 and be done with it.

 

The standard copper NGK plugs (I use the V-power) work just fine on my VG and are cheap. I think I paid less than $2.00 each)

The platinums will last a long time, but I would not run them in an engine that did not come with platinum plugs stock from the factory.

It's plain and simple why you want the copper plugs - Copper has lower electrical resistance than platinum or iridium. In fact, the only other material with lower electrical resistance is silver.

Sure, copper plugs don't last long as platinums, but on a VG, changing plugs are a piece of cake unlike most V6 engines nowadays...

Also, factory recommended spark plug change interval on the VG is 30,000 miles.

If you have a Chilton Manual, it's on page 1-49.
If you have the 1992 Owner's Manual, it's on page 8-6.

 

NGK Spark Plugs are probaly the best brand.
