I am going to get spark plugs for my car. I wanted to know that ones to get? I have 146,000 miles. Thank you.

 

And how much do they cost to?

 

NGK Platinums as per the owner's manual. They are good for 60k. It also seems to be the opinion that coppers are fine but you must replace them twice as often. I am sure this is discussed in more depth in a FAQ sticky.

 

get the NGK vpower copper plugs, they are 1.68 each or something like that. I just finished putting them in my front bank only to realize my 6" extension wasnt long enough to do the rear bank

 

yes its a pain for first timers, but after doing it, next time comes around much better


NGK VPOWER cured my once a day, only 1st startup white smoke..CUZ previous owner was using some AUTOOOOO LITTTES!!!!!!

and no it isn't no gasket, radiator, leak, etc etc etc...

 

my prev owner had boshch plat+4 in there.

 

I'd go with the OEM, which are NGK platinums. THey'll cost you $10-12/piece. I've not tried the copper, but they are much cheaper, even though they don't last as long, so if you don't mind changing plugs a lot they are the more economical approach. don't bother with any of the funky autozone things like the ones with 68 heads and say "SUPAR NAWZ POWAR PLUGZ" on the side Keep it simple and reliable.

 

Just had VIP Auto (a chain here in New England) change my plugs. I'd asked for NGK Plat, but when I came back they'd said they were out of stock and they'd put in Bosch platinum instead -- said it was an oem equivalent, quality plug and they figured I'd be happy paying $4.50/ea vs $14 for the NGK anyway.

They are willing to change them out for NGK for free (if I pay for the parts difference, of course).

I'm wondering big a deal this is -- seems like Bosch is a decent brand too, and I'm in the middle of moving so it'd be a bit of pain to get the car back into the shop now.

Anyone run Bosch and have good/bad experiences to report?

 

id have them change them

 

why? is there hard evidence that says you should only stick with one brand of plugs? I've been running Autolites in my car for about 3 weeks with no problems. If there is a reason, i'd like to know.

 

with super high spark distributorless ignition of the maxima running the correct plug really is essential more so than any other car....cheap plugs will toast pretty quick... Incorrect plugs will most definately lead to ignition problems...someone told even told me premature coil pack failure.

a32 lets see of those autolites stand the test of time.

 

it's logic, for something like plugs, go with recommended.. i didn't use platinums because it costed a lot. i like how i am running, no white smoke startups, everything is smooth...

no only w/ maximas i've herad friends and posts bout using other brand plugs that mess up the engine..

 

Stickies clearly state NGK Plats or Coppers

PRoph

 

yeah, bosch arent any good, the difference is there not engineered for the VQ motor, some people get a spastic idle and they burn out MUCH faster than any other plug if you use it in your engine. people hve varied success, but why risk it. you can use the equivalent bkr5egp which is the platinum coated or something.

 

The Previous owner of my car had Bosh platinum in there and i took them out and when i did my mouth hit the floor.... they were burnt to a crispy white so i took them out cleaned them up re gaped and put them back in and ran it for a week with them in that week i bought new NGK Vpower Coppers and installed them after a week of normal driving... surpised to find again they were burnt to a crispy white .... put the ngks in and after a week i took them out and found a perfect clean and normal running sparkplug.... it could just be my car .... i dont know but it made me stick with what everyone else on the org is saying STICK WITH THE OEM PLUG ..... NGK

 

wow bosch platinums are just $1.99 here..

 

yah, after i bought my car w/ 67K i replaced the spark plugs with bosch 4+, and they did a great job for about 8K-10K.....then i got a misfire one day after accelerating after some railroad tracks

the next day, i took out the bosch(which didn't look half bad) and put in the NGK plats and haven't had a problem since......the prob also could have been related to the fact that one of my coilpacks had broken off at the boot; but i replaced that too

 

I just replaced my factory plugs yesterday with NGK coppers.
I have noticed it idles smother and at a lower rpm level (that could also be cause its a little warmer out.)

 

If I have white smoke even after the car warmed up, plugs could be the problem?

 

Thanks for the input everyone. I do know the stickies say NGK but was curious what specifically were the implications of using other brands.

Anyway, sounds like some good reasons to ditch the Bosch. I'll take it back in and have VIP put in NGK. Now that I think about it I know I did say go with NGK copper if they didn't have any platinum, so I'm a bit annoyed, though at least they were quick to offer to swap them for free.

 

give me more info..

i swear to nGKS after what it has done for me, no white smoke EVER, under any conditions, 1st 2nd start up, pounding it etc.. it really does wonder. i have swtich to the ngk coppers vpower after previous owner used AUTO!!!!!!!!!!!!!!!!!1lites..

if that doesn't do it for you, what would? because i took the car to 3-4 diff't shops and mechanics to decide what was wrong, no leaks, no nothing.. just some gay plugs.. then again it is just my experience...

 

I bought my car a year ago; previous owner said put Bosch Platinium 4; Now after 35000 miles will take a look at them and will have NGK Platinium in case need them. I asked around about Bosch and was told they are better for German/European car than for Japanese cars and they do not recomend them for our cars. So far car is ok; only problem is sometimes when stoping at red light car dies right away after releasing cluth; any idea what can it be? May be the spark plugs?

 

no dbout... trust JAPANESE recommendation... go with the NGKS... vpower is good if ur on budget... and they are said to conduct better plats, just last longer..

take them out fast.. b4 its too late.

 

im running NGK Iridiums and they work perfectly fine for me

 

NGK is defintely the way to go. Just as some have said, the NGK Platinum are good for 60k, whereas the NGK copper are good for 30k. The NGK copper give a better spark at start-up but either is still good. With copper, have to change more often just as someone said.

 

I would def go with the ngk's. if you dont want to spend the 8-14 bucks on the platinums just go with the coppers, they shouldnt cost more than $2 a piece. as far as bosch goes it seems to be that other than vw, audi, porsche prob 9 outa 10 cars i seen runnin with them had misfire and other problems. some imediately, some after 5-10k miles.
