Called the dealer and they said i need ngk platinum plugs at 25 each....WTF


I walked into parts source and got the same patinum plugs for my 03 350z for 12.00


Are teh iridium any better


They should be the same.??????

 

in actual fact, to get the best spark possible you would want to go with copper. platinum plugs just last longer but have less of a spark and even worse for iridium, they just last even longer then platnum but have even less spark. i learned this from neetronics (paul neethling) when i had my wrx tuned. He highly supports copper plugs as they have the best spark and less blow out. The downside to the coppers is that they need to be properly gapped and dont last very long, especially with FI. with coppers you would have to change them at minimum once a year. correct me if im wrong guys. either way you will be fine. just maybe have to be replaced before the recomended 50km or what ever it is.

 

Dealerships always have heavy markup, thats why we call them stealerships silly.

 

i remember agincourt nissan only charging 17 each
i m using NGK iridium currently

 

My car is stock pretty much...so i just got the ngk platinum...MEH, seeems like a good price.....I wish they had the double platinum...But i have never heard of that

copper plugs should be the better plugs for performance...
but copper plugs last not very long...

iridium just last longer...

 

i used the g-power platinum 6 heat-range for about 15K and they were showing minor signs of arcing (which apparently is a bad thing), so i switched them out for the iridium ix in the 7 heat-range and i did notice an improvement on idle. power loss from heatsoak didn't feel as bad either.
