I will soon be replacing the plugs in my '98 SE...has anyone tried Denso Iridium plugs? Any thoughts/recommendations? ed

 

Go with NGK's platnium!!!
Densos are good for Toyotas.
Nissan uses NGK's as OE and if its not broke "DON'T FIX IT"

 

NGK Coppers are much more economical. Although they have half the durability, they cost approximately 5x less. Also, copper plugs actually give a better spark. Since changing plugs isn't too difficult once you know how to do it, go with the coppers like I did; you won't be sorry.

have you noticed better drivability with this better spark? I hear everybody say it, but nobody says, it feels like the engine is stronger.

 

i run densos

pricey but i like them

 

I've got bosch platnum +4 i've heard bad things so i'm switching to NGK next tune up in janurary. Do they make platnum ngks?

 

That's the thing with sprak plugs. How different can they be in terms of power? 1-2hp at most if you're lucky, for an NA car. The main difference is longevity.

If you're running boost, then the spark plug types, copper, platinum etc, will play a bigger factor in the mod game.

I have the denso iridiums, no big deal. Better spark doeesn't really do anything but make the car run and fire better and they last longer. They don't add horse power or anything.
Just get spark plugs that work well. NGK are specifically for nissans I think. But if you get denso's or NGK's it won't make a difference. Just make sure you tighten them right.

 

Yes, NGK platinums are std equipment. ed

 

You can pick them up at your local dealer.

I'm not looking for huge HP gains...if they result in better driveability and last as long as the stock plugs, then I'd consider that a win. Will probably just stick with the recommended NGK's. I agree on the tightening...I always use a torque wrench for these occasions. ed
