Which is the best spark plug for my '96 Max? I have those 4 prong Bosch Platinum ones in there now with over 60k on them. Was thinking its about time to change them. Suggestions anyone?

 

60K from Bosch Plat +4 plugs? Holy sparkplug Batman


Get yourself the NGK plugs and NEVER use anything else.












Oh and consider yourself very lucky that you got that kind of mileage on Bosch plugs.

 

NGK Plat. is the way to go.

 

NGK!!!

 

I asked the same question yesterday, there is someone on the board that will sell them to you for $45. I just bought mine from DaveB (with a knock sensor) for just $52, and he shipped them with the Knock sensor.

Someone told me exactly why the Maxima NEEDS NGK platinum, something about reverse polarity.....

 

Care to elaborate?

Btw, who's selling the plugs? $45 shipped?

 

I just purchased NGK double IRIDUIM for the same money as ngk platinums spoke with engineer at ngk facilities in Jersey gave me the plug numbers and recommended these said they're a better plug use less voltage and durablility was better longevity was 80-100,000 miles

 

I was told that if u use platinum plugs with SC setups, u'll mess your car, so cold step copper is it, if u got a SC.

 

I'm using a SC and N2O and JWT told me the stock NGK plat. plugs are all you need!!

 

ive used bosch coppers in my car, without any performance lost. i swapped them out for some denso iridiums, and they looked fine after 10k...

 

I just replaced my stock NGK plugs with one step colder NGK PFR6G-11s last night after 75,000 kms. I installed the V2 SC on Oct.10, 2000. I started to hear pinging when accelerating hard lately. I looked at all of the plugs and 5 out of the 6 had a reddish-brown dusting on the electrode and the firing end. Checking the end cover of the Haynes manual suggests that these were either worn or not in the correct heat range. The sixth plug had some small amounts of ash deposits on the sides and center of the electrode. This could be because I was using 87 octane for a year before finding out that I should be at 92 octane or better but shouldn't all of the plugs have the same results?

I spent 3 hours on this job because first the Blitz BOV had to be removed in order to slip off the valve cover. Using an Allen key in the cramped space between the screw and the hot valve cover was fun . Putting it back on was equally fun too.

The worst part was the last plug by the throttle body. I thought I could slip out the coil without moving it and the FSTB but when I tilted the coil the rubber boot came off. Sticking the coil back in did not reseat the boot and so I moved the part that sat above the coil and the loop that the throttle cables pass through, cut up a coat hanger and make a loop at one end so that it is the same diameter as the coil tip bump. After a few tries and body contortions I got it out.

All in all, with the proper tools it is actually quite easy to do.

 

Hey all.... Thanks for the info!!

 

That's what I heard, too.

Anyt truth to this?

Doesn't matter anyway, I already bought the colder coppers.

 

ngk are the best. i got mine for $60 at the dealership but im pretty sure you can get them cheaper some where else

 

I can't believe how the Plats make the engine run so silky smooth now.
I went for a few hot bursts near my place and there was no knocking at all.

 

 

whats the point of this >

 

Bumping a 6 year old thread because you can't tell the difference between spark plugs and injectors, priceless.

 

that is some fuel rail you have there lol

 

 

oh jebus cripes!!!

 

now watch him take out the injectors and try to stick spark plugs in there

 

lmao
