just wanted opinions on what the best spark plugs are for a 4th gen. some people say iridium and all that doesnt matter....want more opinions.

 

ONLY USE NGK!!!ONLY USE NGK!!!ONLY USE NGK!!!

Either coppers (NGK BKR5E-11, about $2, last 30k miles), or stock plats (don't remember part number, about $10, last 60k miles). I use coppers since they're alot cheaper and I change them myslef. If you are having them changed it's probably cheaper in the long run.

 

3 letters: NGK

 

for the stock platinums, should i jjust goto the dealer? if so ill just order from jerry rome

 

I had denso iridiums and they fouled real bad in about 5K miles. They are only good on boosted or nitrous applications. My car seems to run best on NGK vpower copper.

 

JR's where I got my coppers.

 

I use 1 step colder NGK coppers

 

i guess everyone is using coppers... has anyone had a bad experience with platinum NGK's before???

 

Are you boosted? If not then why?

 

^look in his sig theres a pic of a turbo on his car

 

No need to go colder, etc. Coppers are cheaper - which is why a lot of people here have them. I run plats in my car - but its a personal choice - you'll find plenty of opinions on why use the copper over platinums... key word in that sentence was opinions. If you do go the platinum route - just order from jrnissanparts.com (Jerry Rome Nissan) - use the "maxima" promo code for an additional discount.
