I'm planning on buying some new spark plugs and I need some help. First off, what kind should I get? NGK? I've searched and found that platinum ones go on the Maxima, but is that it? Are there iridium ones for our cars?(I'm asking because I heard iridium is better.)Finally, where should I buy them from? I know you guys are going to say "search! search!" but I did and it wasn't very effective. Any help would be appreciated.

 

The correct plugs are NGK-PFR5 (or something like that, don't remember the exact part number). They are called NGK Platinum plugs, and the box says "Laser platinum" on it.

Stick with the stock NGK plugs (the ones I listed above). They perform best for our cars.

 

Stick with the stock plugs, if $$ is a factor, then go with NGK copper, only thing is that they don't last as long. Iridium will only last longer, not anything else. Just get the stock ones from courtesy for about 60 bux total. Unless you're pushing N2O, stick with above metnioned heat range/part #

 

Use the stock NGK PFR5G-11. Try tustinnissan.com like $8.80 each mention maxima.org for a discount.

New plugs made a huge diff on my '97 with 65K miles on the old plugs.

 

NGK Platinum all the way... my dealer charged $11 a piece and I didn't hesitate for a second.
