im gonna be changing my spark plugs, but ive been reading the copper ngk's get better spark than the platinums. why?

also, would it be beneficial to use ngk iridium ix on our generation vq's?

 

I just changed my plugs and used copper cores. They lasted a few milesbefore I noticed a slight "miss" in the engine. I immediatly switched them to the iridium type of NGKs. I believe the IX iridium NGKs are about $5-$6, but I opted for the $10 iridium NGKs instead. My mechanic recommended them, I figure my baby deserves the good sh*t anyways! Don't step over a dollar to save a nickel.

 

I've been using NGK coppers with good results.

 

stick to the OEM Nissan plugs, they work best...

 

Bkr5eix-11

 

Are OEM's copper or platinum?

 

Platinum #PFR5G-11

 

Thanks, that's what I'm getting.

 

I heard that oem plugs are really ngk's.

 

NGK Platinum

 

I am using Bosch Platinum + 4's and have about 75,.000 miles on them with no problems at all so far.

 

I agree. I never saw the difference in other plugs myself...except for the price.

 

I suspect you don't know how the engine is supposed to run, as your statement is in the vast minority of experience members have had with those plugs.

 

those plugs suck on NISSANS (and most Japanese Cars), they work better on european cars (VW, BMW, etc.) maybe you got lucky and actually got a good batch of plugs, but in my case I had them in for 6 months and they robbed my car of power, switched to NGK Plats, my MAX runs great now.

 

well I got some NGK's last week when I went to NAPA to get them they had some platinum for $6 and some other platinum for $11.I got the cheaper ones but the engine sounds stronger.What are the diffrence between these and how much longer would the more expensive ones last?

 

twice as long...
