whats the best way to tell if your spark plugs need to be replaced and also what are the best plugs for the max and where to get them

 

how many miles on um?
bests plugs are the factory ngk's i forgot part# but someone on here will tell u, infact it think its on www.sprintmax.com write up. they are on ebay for about 40$

 

PFR5G-11 for the Plats. Not sure 'bout the coppers tho.

 

BKR5E-11 for NGK V-Power Copper plugs and they're about $2/each. Got mine at NAPA for $12 something with tax

 

just double check the gap, even though they are pregapped it may be off.. I did when I changed mine and they were all completely off..

 

Mine were pregapped fine Remember to use anti-sieze for the plugs.

 

i have 70k on my 95 now and im sure the previous owner never changed them, would new plugs make a difference here?

 

If you have money, get the NGK plats ($37 for 6 on eBay, $15 each from dealer), but if you're low on cash (like me) use NGK copper plugs (only like $2 a piece).

 

How much does it cost to have them replaced? (Labor (I'm not up on the do-it-yourself mait.))

 

Yikes if you can't change ur own plugs... don't know what to say

it should not be more then 50$

 

Is it hard to do? I just don't wait to screw my baby up...

 

I'm 17 and I did it myself (actually, I did it when I was 16) It's not hard at all! Go try it out and it'll make you want to fix up other things on your car

 

There is dirt on the side the spark opening. How do you prevent dirt from getting into the engine?

 

On my ' 98 Max ( auto tranny) I can`t decide on spending 18.00 $ on a single OEm NGK PFR5G-11 platinum spark plug, as opposed to the reguler copper NGK BKR5E-11 at 3.00 $ ( canadian prices). I prefer changing plugs every 2 years or 40000 km at 3$ a plug, as opposed to 18$ a plug every 5 years / 100000 km. Besides, I dont plan to keep the car another 5 years, perhaps 2-3 years.
On the other side, previous posts have praised the platinum plug, very mush so. What would you do?

copper plugs spark better but do not last as long, i would go copper at 3$ canadian

 

That's what I'll do. Worse scenario it would have cost only 3$ x 6 = 18 $ plus tax to try them out.

 

I got the copper plugs for $12 total and those will last me 30k and the platinums are $37 shipped from eBay and those last 60k. For that price I can change the copper plugs 3 times for a total of $36 and get 90k out of the 3 sets Talk about saving money

 

I use NGK BKR6E-11's (one step colder, because I'm boosted) coppers and change my plugs every 3,000 miles along with my oil.

They're so cheap and it's so easy to do, i don't see why not!

 

Are y'all gapping the coppers at .044 (at least I think that is what the platinums are supposed to be gapped)? Or does a little more or a little less gap make any difference at all?

Thanks

 

Mine were pre-gapped perfectly fine. I double checked

 

gapped at what??? I have searched almost everywhere and cannot seem to find if the gap on the copper plugs should be the same as the platinum.

I will go with stock gap unless anyone has any suggestions.

Thanks

 

.044 inches for all spark plugs for a 4th gen MAxima. Visit www.ngk.com all the gap specs are shown per vehicule application. very useful

 

what do you use to gap the plugs? what else would i need to buy to do them myself like tools and supplies like anti sieze?

Question!

Does the quality of the spark plug have any correlation with the fuel econony? If i change my spark plugs to platinum, will the gas milage go up?

There some reqular and platinum plugs you can choose from. I had the regular spark plugs and my car is eating alot of gas. Any thoughts?

Max 96 GLE

 

You can buy a spark plug gapper from any Auto Parts store. The cheap ones run like $.99 and are still somewhat accurate.

The really nice ones run quite a bit more, and are super accurate.

The $.99 ones have always worked for me anyway.

I gap mine to .036, because of the extra hp from the blower.

 

My sorry butt didn't even think of checking w/NGK. Man, I must be getting old......

Thanks for clearing up my question.

 

Wow! And I thought I was **** for changing my BKR6E-11's after only 15000 miles.

 

3000 milles interval for changing spark plugs is an overkill to me unless you race the car and earn a living from racing.

 

BBIIIGGG Difference. You'll be amazed.

 

It's overkill for me too - but it's cheap and why not....

 

How did you folks put out the spark plug cable without putting out the cable plug? Any suggestion?

 

???????????????

 

The cable plug that connects to the spark plug appears to easily put apart on my old Mazda. I’m curious, if it would be the same on Max cable.

 

If you have a 4th gen MAxima, then it has no distributor. Each spark plug has it's own coil. There are no high voltage cables that run from the ditributor to each spark plug, like older engines.
There still are wires that go on each coil on each spark plug. These coils have to be unscrewed to to be pulled off each spark plugs. Very easy to do. Also disconnect the wires that run on each coil before removing the screws.

 

ok, thanks.
