Today i went to autozone, my car is 2k maxima. i decided to get a tune up because eversince i got my car at 90 xxx miles on it, i have never change the spark plugs and now its 162xxx so i plan to get NGK V-Power for 4.99 But they were out of stock then the dude told me NGK Iridium for 6.99 so i was like okay but then wen i got home it was Autolite XP Iridium and my car is N/A. So my question is..is Iridium better than Copper n Platium? and what do you guys think about Autolite? does it affect much? I just don't want it to destroy my engine. my car has 162 xxx already so yeah gimme some thoughts please.

 

Iridium plugs last longer, otherwise the performance should be the same.

 

Damn what state is that I got my NGK Iridiums for 8.49 in Cali...and had to go to 3 Autozones to get em' but they are worth the money, I check like 20 to 25,000 miles cause who knows how long spark plugs is suppose to last especially a 100,000 miles and when you pull them out there all burnt to a crisp...Good Luck though....

 

Plat. or Iridium will be fine, but I don't believe you'll see any difference really between the way the two perform. I would personally only recommend NGK in the Nissan.

 

NGK Copper's
