i have NGK double platinum. there is 26.000 ml on them and they 5 years old. i know on owr maximas they have to be changed evry 60.000ml + or -.
should i change them or i m ok.

 

probably ok, just take one out and have a look at it. if it looks clean, leave them in. if they look dirty or rusty, replace. it's a cheap, easy job, just did mine.

SORY FOR MY SPELLING .I M DAMN RUSSIAN. WHAT CAN I DO. lol they checked it at the shop,they pull out one,and they tolld me they r good.i gues i ll be chenging them in 5 years,couse i m puting like 5000 ml per year.lol

 

Change them anyway .. 5 years old .. I would do it when I was bored since it's not mandatory.

 

Are you racing your car or is it just a daily driver? For a daily driver you are fine. Keep those spark plugs in there at least another 15,000 miles (assuming your car is not having any problems that you think relate to the engine or spark plugs).

If you are really worried about them, you can always check them out to see if they are okay.

Many maxima owners with 100,000+ miles are still driving around on their ORIGINAL plugs. I don't recommend that, of course. I'm just saying that yours should be fine.

 

my race day r in the past i m driving like an old lady,i think the fastes i was ever driving this maxima 75 on the hwy. like 3 times.my old maxima that was another case. i m driving like 6 ml per day. and may be another 30-40 ml on weekend,in brooklyn ny u can't go to fast even if u want to, so my speed is like 30-40 in the sity and like 50-60 on hwy. i m to old for that sh...t u know lol

 

COme on man the Max is meant to break the spedometer :P I went 140 on the highways racing this stupid Focus :P stupid focus people pshhhh.(Beat him of course) Can't they understand that Maximas are Focus Killers and im surprised my car didnt break down on me considering it has 173,664 miles on it. Anyways i dont know if NGK is better than Denso im guessing they are. I have the Denso Iridiums. If NGK are better let me know so i can look into getting them on the next spark change.

 

u dont need iridiums if your not boosted and ngk is the recommended spark plug for us.. read the stickies

 

OK cool thanx sorry im still noobie to this ill get around this site thanks for letting me know though

 

no problem

 

You're only 34 you pansy.

 

I'm just agreeing with you. I'm at 104k on my original plugs. I also think it's a bad idea, and am picking up new plugs next week.

 

k after hearing all your complains i did it . i was going 105 mp/h for about 10min on the hwy,my friend who is the cop was sitting next to me,so i wasn't worrying about any tickets, man it felt so grate. "KIDS DON'T TRY THIS AT HOME" LOL

 

By "did it", do you mean replaced your spark plugs? If so, okay. But your plugs surely had more life left in them.

Of course, it's always nice to know that you are running at 100% performance. Although you were probably still at 99.9% peformance before since your plugs were probably fine...

 

Do u guys notice any major difference between the NGK VPOWER and NBK Platinum for out cars?

People saw the VPOWERS conduct better cuz its copper but the PLATS last longer. However, I was just curious if the plats really matter that much interms of performance, afterall it is the recommended PLUG type to use ??

I changed mines to VPOWER from 'autolite' and I noticed that it 'seemed' smoother, though my car has always been in good running condition. Maybe I'll try the platinums next time. About how much are they for 1 piece? I don't mind changing plugs cuz it's easy.

 

I had NGK Platinums and just switched to copper and it runs just as good as before. I figure for costing five times less and only having to change them twice as much I am gonna stick with the coppers from now on. But that's just me.

 

JUst put new sparkplugs NGK of cousrse which you could buy in EBAY really cheap!!!!!!!!!

 

AND GET IRIDIUM IX spark plugs youll feel the difference

 

I know I did :

 

I suspect your car doesn't run particularly strong and your fuel economy must suck. Change those plugs before you have to get them machined out of that aluminum block!

 

I had Bosch 4 Platinium that were supose to last 60,000; I replace them as per got check engine light at 55, 000, they were totally destroyed, burned, etc.. I will never believe or wait for 60,000 again. Put the NGK copper $1.68 each and car feels better and got and extra 20-30 more miles per tank. Will chance in 30,000 miles. That means every year.

 

Well, thats not fair they were bosches

 

you could just check them at 30k

 

My OEM NGK laser platinum plugs have 59,765 miles on them and are going strong. My fuel economy is still better than just about every 4th Gen on the .org.

 

How exactly do you "CHECK" platinum tipped plugs? I suppose we should re-gap them too right?

 

Ya, and also inspect the bearings and re-grease the tips too...

 

no my spark plugs r good.
" i did it" i was talking about 105 mph

 

I'm glad. Would be a shame to toss perfectly good platinum plugs...
